FIND YOUR FIT—Women’s Karate Gi Size Guide

Onna Kimono is proud to present Musha, a line of karate uniforms designed specifically for female warriors.

In pre-modern Japan, the Onna-musha were women who fought alongside samurai, proving their strength, discipline, and skill. We believe today’s women karate-ka deserve the same respect — starting with a uniform that fits, moves, and supports real training.

Women’s bodies don’t fit neatly into traditional “unisex” gi sizing. That’s why Musha uniforms are built around female proportions first, then refined through fit options that allow you to train without distraction.

Step 1) Start With Height (Yes — Really)

Our sizing begins with your height in centimeters (cm).
This determines your base size.

Unlike traditional size charts, you do not need to size up just to get room in the hips or seat — that space is already built in.

Step 2) Choose Your Fit

We currently offer three fits to better match real female bodies:

Standard Fit—Balanced, athletic, and versatile. 

Measure the fullest part of your bum. If the measurement is between 40”-50” you are a Standard Fit.

The Standard Fit Musha gi is designed for the average American female frame. It offers:

  • extra room in the hips, thighs, and seat

  • reduced fabric at the shoulders

  • a modified bust shape for comfort and mobility

This fit delivers a tailored feel without sacrificing movement or affordability.

(Typically works well for women who wear size 8–16 in casual clothing)

Curvy Fit—Room to move, power to train

Measure the fullest part of your bum. If the measurement is between 50”-60” you are a Curvy Fit.

The Curvy Fit is designed for women who need more space through the hips and thighs to train comfortably and confidently.

This fit supports full range of motion without restriction — no pulling, binding, or constant adjusting.

(Typically works well for women who wear size 12–20 in casual clothing)

Slim Fit—Strong, streamlined, and fast

Measure the fullest part of your bum. If the measurement is less than 40” you are a Slim fit.

If you’ve ever felt swallowed by fabric, this fit is for you.

  • narrower shoulders

  • cleaner lines through the torso

  • less bulk without sacrificing strength

No shoulder seams halfway down your arm.
No drawstring digging in.
No excess fabric slowing you down.

(Typically works well for women who wear size 0–8 in casual clothing)

Adult Slim Fit is available in select sizes.
Youth sizing (120 cm thru 150) follows the Slim Fit chart.

Step 3) Size UP or Down (Optional)

Fine-Tuning Your Fit

We offer ½ sizes to help dial in sleeve and pant length. That is to say that if your size is OUT OF STOCK you can easily size up or down for slightly shorter or longer sleeves since the difference is only a few cm.

Please Take Note!

Our Black Edition gi are 100% cotton and will shrink slightly — because cotton does what cotton does. The Musha Blue does NOT shrink as this particular fabric has been pre-washed.

You also have 30 days to return or exchange if something isn’t quite right.

Custom Orders—When Standard Sizing Isn’t Enough

We use height-based sizing and fit options (Slim, Standard, Curvy) to accommodate a wide range of bodies. Bust measurements help identify when a standard fit may not work as intended.

If you have a larger chest and a narrower waist, you may find that a jacket and pants require different fits for comfort and performance. This is called Split Sizing. 

Once per year, we open a limited custom ordering window that allows split sizing or non-standard combinations.

Custom ordering opens annually in late spring.
