Bra Size and Fit Guide
Every bra fits a little differently. Our bras come in sizes XS to 3XL, but each style covers its own range of bands and cups. Measure once, then see the styles that fit you and your size in each.
Compare our styles
Not sure where to start? Each style is made for a range of cups. The Pointelle Bra covers both.
For cups A–DLighter shaping, more styles to choose from
For cups C–GFuller cups, built for more bust
How to measure
Use a soft tape measure and wear an unpadded bra or no bra. Keep the tape level all the way around.
Under bust (around your rib cage)
Measure snugly right under your bust, where a bra band sits. Breathe out and read the number. This decides your size in each style.
Chest / bust (at the fullest point)
Measure loosely around the fullest part of your bust, without squeezing. Stand straight with your arms relaxed.
Work out your cup
Take your under bust away from your bust. Each inch of difference is one cup size. The size finder does this for you.
| Difference | 1" | 2" | 3" | 4" | 5" | 6" | 7" |
|---|---|---|---|---|---|---|---|
| Cup | A | B | C | D | DD/E | DDD/F | G |

How do organic cotton bras compare to synthetic bras?
Organic cotton feels softer and less restrictive, while synthetic blends may offer more stretch or compression.
Organic cotton bras can still feel supportive, but the support feels different and may take some adjustment if you're used to synthetics.
Do you have plastic free bras?
Yes, our Full Bust Sports Bra and Crossover Nursing Bra are plastic free. Our Criss Cross Bralette has a plastic free option (Natural with Bioelastic).
Please note, our plastic free bras are not suitable for those with latex allergies.
Are your bras GOTS certified?
All of our bras are GOTS certified, with the exception of our plant-dyed styles. While these are made using GOTS-certified organic cotton, we currently work with a dye house that is not yet GOTS certified. We're actively working toward full certification across these styles as well.
How should I wash organic cotton bras?
Wash in cold or warm water with gentle detergent and avoid bleach or fabric softeners to maintain softness.
Why choose organic cotton bras over regular cotton?
Unlike conventional cotton, organic cotton avoids toxic dyes and pesticides, reducing skin irritation and supporting healthier, more sustainable farming practices. To learn more about our certifications click here.
Do organic cotton bras help prevent rashes?
Yes, its breathable, chemical-free fabric helps reduce moisture buildup and irritation, which can lead to rashes.
What's the difference between 95% organic cotton and 100% organic cotton bras?
The main difference comes down to stretch and structure. 100% organic cotton bras are made entirely from natural fibers, offering maximum breathability and a soft, natural feel; ideal for sensitive skin. However, it has less stretch.
95% organic cotton bras have a small amount of elastane, which adds stretch, flexibility, and helps the bra maintain its fit after washing. This blend moves with your body and stays in place throughout the day. It's a great option for sports bras or styles that require a bit more stretch.
Both options are safe and comfortable.
What bras have openings to insert a bra pad?
Our criss cross bralette, racerback sports bra, and crossover nursing bra all have openings to insert a bra pad if you prefer.
