Find Your Fit at Peter Kate
Designer sizing is not universal, and Peter Kate is here to make it feel much less mysterious.
Maybe you are a small in one brand, a medium in another, and suddenly checking centimeters like you are packing for a week in Paris. That is normal. Fit changes by designer, silhouette, fabric, stretch, and the way you like your clothes to sit on your body.
Use this guide to compare popular Peter Kate brands, check the measurements that matter, and choose pieces with a little more confidence before you order.
Start With Your Measurements, Then Add Your Style Instincts
A size chart is a helpful starting point, but it is not the whole outfit. A structured blazer, a relaxed button-down, a fitted dress, and a pull-on jean all ask different questions of the same measurements.
Start with the basics, then think about how you want the piece to feel. Close to the body? Classic and easy? A little relaxed so you can move, sit, and enjoy the whole day without thinking about the seam at your waist? Good. That is fit.
How to Measure Without Making It a Project
- Bust: Measure around the fullest part of your bust while keeping the tape level.
- Waist: Measure around the narrowest part of your natural waist.
- Hips: Measure around the fullest part of your hips.
- Inseam: Measure from the top of the inner leg to where you want the hem to land.
- Foot Length: Trace both feet, measure heel to toe, and use the larger foot when checking shoe charts.
Inches are usually the easiest place to start for apparel. Centimeters are especially helpful for European shoes, and they can be the difference between walking all day through Montreal in the fall and wondering why your feet are writing you a strongly worded letter.

Veronica Beard is polished, tailored, and very good at making a weekday outfit feel like you had a plan. Think blazers, dresses, denim, and pieces that move easily from a client lunch to a gallery opening or a long weekend away.
Fit Note: Veronica Beard offers different size guides by category, including general clothing, dresses, jackets, denim, pants, and shoes. For structured jackets, start with shoulder and bust fit, then think about sleeve length and how much room you want for layering.
Peter Kate Fit Tip: If you are choosing a Veronica Beard blazer, prioritize the shoulder. A sleeve can be styled, cuffed, or tailored, but the shoulder tells the whole story.

L’AGENCE brings that polished Paris-meets-Los Angeles feeling Peter Kate shoppers love. The pieces often feel sleek, feminine, and modern without looking overworked.
Fit Note: L’AGENCE sizing can vary by style, especially across denim, blazers, dresses, tops, and knits. Check listed fit notes when available, then think about whether you want the piece close, classic, or more relaxed.
Peter Kate Fit Tip: For L’AGENCE denim, do not shop by waist alone. Rise, leg shape, stretch, and where the hem hits all matter. A cropped jean on one shopper can look ankle-length on another, and that is exactly the kind of detail worth checking before you order.

Simkhai is a strong choice when you want clean lines, interesting shapes, and a refined finish. The brand works especially well for dresses, knitwear, jackets, denim, and event-ready pieces that still feel wearable.
Fit Note: Simkhai uses separate charts for women’s numeric sizing, denim, and footwear. Its women’s size guide maps U.S. numeric sizes to alpha sizing, so a U.S. 6 falls under medium on the published chart.
Peter Kate Fit Tip: For Simkhai, pay attention to the category first. A knit, a blazer dress, and a denim style will not all behave the same way, even if the label says the same size.

rag & bone is made for the woman who likes sharp everyday pieces with a little city attitude. The look is cool without trying too hard, especially in denim, shirts, knits, and easy layers.
Fit Note: rag & bone notes that size charts provide general sizing and can vary by style. That matters most with denim, pants, and Miramar pieces, where fabric, stretch, rise, and intended ease all change the feel.
Peter Kate Fit Tip: Treat Miramar like its own category. It can look like denim while feeling softer and more relaxed, so the best size depends on how much drape or structure you want.

Rails is easy in the best possible way: soft shirts, dresses, denim, and relaxed layers that still feel pulled together. It is a lovely brand for travel days, school events, casual offices, and weekends when you want comfort with polish.
Fit Note: Rails uses an inch-based women’s chart for bust, waist, and hip, while individual styles can have their own fit recommendations. That means a shirt, dress, cropped jean, and barrel silhouette should not all be judged from the letter size alone.
Peter Kate Fit Tip: Think about desired ease and hem placement. A cropped jean that works at one height may become ankle length on another shopper, even when the waist size is right.

FRAME is a go-to for clean denim, polished basics, and pieces that feel modern without getting too loud. It is especially useful when you want an outfit to feel sleek but still comfortable.
Fit Note: FRAME is often about proportion. For denim, look at waist, rise, inseam, leg shape, and stretch instead of choosing from waist size alone.
Peter Kate Fit Tip: If you love a longer line, FRAME can be beautiful with a tucked blouse and a clean heel. If you are petite, watch the inseam and where the knee breaks so the shape still feels intentional.

Frank & Eileen is easy in the best way. The shirts, layers, and relaxed staples feel made for travel days, polished errands, casual offices, and that just-threw-this-on look that somehow still feels considered.
Fit Note: Pay close attention to body length, sleeve length, and the amount of ease through the torso. Frank & Eileen can be especially friendly for petite styling when the proportions land in the right place.
Peter Kate Fit Tip: A designer button-down does not need to feel corporate. Roll the sleeves, add a relaxed half-tuck, and wear it with denim and Back 70 sneakers. Then give it a sharper mood with a blazer, pumps, and statement jewelry from Jane Win and more.

A.L.C. brings modern structure, confident color, and pieces that feel ready for real plans. The dresses and separates work especially well when you want a look that feels intentional without feeling precious.
Fit Note: A.L.C. fit changes by silhouette. A tailored dress, a soft knit, and a sculptural top will each sit differently, so compare bust, waist, and hip measurements before deciding.
Peter Kate Fit Tip: If one measurement is between sizes, let the most fitted part of the garment make the call. A defined waist or close bust usually needs the most attention.

Cara Cara is color, print, and vacation energy with polish. The dresses and sets are beautiful for showers, garden parties, destination weekends, and any day that could use a little sunshine.
Fit Note: Cara Cara charts often use both alpha and numeric sizing. Defined waists and fitted bodices deserve a closer look, especially if you are between sizes.
Peter Kate Fit Tip: Let the print lead. Choose the size that fits the bust and waist comfortably, then keep the accessories focused with one polished shoe and one structured handbag.

Fifteen Twenty is a lovely fit for women who like modern separates, wearable dresses, and polished pieces that do not feel overdone.
Fit Note: Fifteen Twenty publishes numeric and alpha measurements for bust, waist, and hip. Use those three points together instead of choosing from the letter size alone.
Peter Kate Fit Tip: Fifteen Twenty is especially useful for outfit-building pieces. Think a top with slim pants for work, then a different shoe and handbag for a museum afternoon, relaxed cocktails, or a Saturday in the city.

Farm Rio is joyful, colorful, and made for shoppers who are not afraid of a print. The styling feels vacation-ready, but the right piece can still work beautifully for daytime events and warm-weather plans.
Fit Note: Farm Rio recommends comparing body measurements with garment measurements and considering the intended design. An oversized dress should have more room than your body measurement, while a closer stretch style may sit nearer to the body.
Peter Kate Fit Tip: With Farm Rio, decide where you want the print to sit and move. If the dress has a defined waist or fitted bodice, make that your starting point.

Doen has that soft, romantic quality that feels like it already belongs in your closet. Think vintage-leaning shapes, gentle prints, and easy dresses you will want to wear on repeat.
Fit Note: Doen can feel different depending on the cut. A smocked or relaxed dress gives more ease, while a fitted bodice or waist should be checked against your bust and waist measurements.
Peter Kate Fit Tip: If you are between sizes and the style is fitted through the bust, sizing up is often more comfortable. If the style is relaxed, your usual size usually keeps the shape.
Shoe Sizing, But Make It Vacation-Ready
European sizing shows up often in designer shoes, and it is much easier once you treat centimeters as your friend. Trace both feet, measure the longer one, then compare that number to the chart. Very French vacation of you, honestly.
Back 70 sneakers are casual, cool, and just playful enough to take a polished outfit down a notch without making it feel sloppy. They work with denim, relaxed button-downs, soft dresses, and travel layers.
Fit Note: Back 70’s women’s chart uses European sizes with foot length in centimeters. Several Back 70 styles are listed as true to size, but the centimeter measurement is still your best starting point.

Handbag Scale & Carry Fit
Handbags do not need an apparel-size conversion, but scale still matters. The question is where the handle rests, how the strap hits, and whether the shape feels right for the day you have planned.
MZ Wallace is a Peter Kate favorite for travel, work, and everyday organization. The most helpful details are size, weight, strap range, laptop capacity, handle drop, and carry method.
Peter Kate Fit Tip: Think about what the handbag needs to hold before you choose the size. A compact crossbody and a work-ready tote solve very different days.
Clare V. handbags are all about shape, scale, and personality. Adjustable and interchangeable straps can change where a handbag rests, which is why length matters just as much as width and height.
Peter Kate Fit Tip: If you are petite or prefer a cleaner line, check strap drop and crossbody length first. If you love a larger carryall, compare the height against what you usually reach for every day.
Compare Measurements, Not Just Labels
A familiar size gets you started. Measurements and fit preferences get you closer.

This chart is a general brand comparison, not a final answer. Fabric, construction, stretch, and intended silhouette still affect the fit, which is why a Peter Kate stylist can be so helpful when you are deciding between two sizes.
Personalized Fit Support, The Peter Kate Way
Size charts are helpful. A real person who knows the designers is even better.
The PK Girls can help you think through the part the chart cannot see, like how you prefer a blazer to sit, whether you like denim close or relaxed, or how a dress should feel when you are walking, sitting, and actually living in it.
Send the style you are considering, your usual size, and how you like your clothes to fit. Peter Kate can help compare brands, talk through silhouettes, and guide you toward the size that makes the most sense.
Contact Peter Kate customer support for sizing help before ordering, or browse Peter Kate designers when you want to compare brands by style, fit, and mood.
FAQ: Designer Sizing & Fit Help
Why Am I a Different Size in Different Designer Brands?
Each designer builds around different proportions, fabrics, silhouettes, and fit preferences. A familiar number or letter can mean something different from one brand to the next, which is why measurements matter more than the label alone.
Should I Size Up When I Am Between Sizes?
It depends on the piece. For a fitted dress, structured blazer, or non-stretch waistband, choose the size that gives enough room through the most fitted area. For a relaxed button-down, easy knit, or elastic-waist style, your usual size may preserve the intended shape.
Should I Use Inches or Centimeters?
Use inches for most apparel charts and centimeters when a shoe chart asks for foot length. Think of centimeters as the travel friend who actually read the itinerary: a tiny bit precise, but very useful once you are walking through a European city all afternoon.
How Do I Use European Shoe Sizes?
Start by tracing both feet, then measure from heel to toe. Use the longer foot when comparing to the shoe chart. If you are between sizes, consider the shoe shape, whether the toe is pointed or rounded, and whether your foot prefers a little extra room.
Can Peter Kate Guarantee the Fit?
No size guide can promise a perfect fit for every body, fabric, or personal preference. Peter Kate can give you a stronger starting point with brand-specific guidance, measurements, and stylist support before you order.
Find the Size That Feels Like You
The best fit is the one that lets you stop adjusting your clothes and enjoy where you are going. Maybe that is a workday, a weekend trip, a wedding weekend, a European vacation, or a romantic walk through Montreal when the leaves are doing their thing.
Start with the chart, add your measurements, and let Peter Kate help with the styling eye. When your clothes fit the way you like them to fit, everything else feels easier.
Ask Peter Kate for sizing help or shop the designer edit with a little more confidence.
