No code necessary, discounted price as marked.

Orange butterflies scatter across a pink background in our Mariposa print, a nod to changing bodies everywhere. Pick your contrast: Blush, Tan, Bronze, or Deep Brown.

The back straps come up and over the shoulders and travel straight down the back, so soft and gently supportive you’ll barely know they’re there.

All OOMBRAs are super soft and completely reversible, made from a patented design that hugs without binding. Our jersey fabrics won’t trap smells or irritate skin like synthetics used in athletic wear. 

OOMBRAs never have hardware – no clips, clasps, strap adjusters or wires - so there’s nothing digging into your skin or underboob! 

Our sizing is unique! OOMBRAs use a simple single-measure system to fit a wide variety of body shapes - YES, our bras work for flat chests and curvy ones, too. To find your size, use a soft tape measure, wrapping it around the biggest part of your bust, including your nipples. Don't pull tight! The number of inches around is your OOMBRA size. If you're on the cusp between 2 sizes, we definitely recommend going BIGGER.

And for lots more sizing info, check out our sizing page.

The OOMBRA is designed to be worn on both sides. Yes, it’s totally reversible! The same super soft jersey is used for the nude and print fabrics, so it's always gentle against the skin. Meanwhile, a middle panel does the work of hugging the boobs without lots of pressure against the chest. The OOMBRA represents a design collaboration between a pediatrician who knows what’s good for growing and changing bodies and a lingerie designer who knows how to make garments functional.

FABRIC: Our super soft exterior fabric is made from 46% cotton, 45% Modal, and 9% spandex.
What is Modal you ask? It’s a monofilament fiber that makes fabric buttery-soft and cool to the touch, so cozy. It regulates moisture for comfort, which helps inhibit bacterial growth and stink. Modal is made out of beechwood trees so it is 100% biodegradable, which also means no microplastics!
The inner layer is a special knit 100% poly, giving the coverage wearers want.

CARE: We recommend hand washing your OOMBRA in warm water and laying it flat to dry. But you can absolutely throw it in the washing machine and tumble dry low, too.
