The OOMBRA is designed to be worn on either side. Yes, it’s totally reversible! The same super soft jersey is used for the nude and print fabrics, while 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 boobs and a lingerie designer who knows how to make garments functional.

To measure your OOMBRA size, just use a soft measuring tape and wrap it around the biggest part of your chest, including your nipples. Or check out this chart to convert from other bra sizing to OOMBRA sizing.



Each OOMBRA size covers a 2" span. If you are right on the cusp between sizes - let’s say you measure 30" exactly - then choose to go with the bigger or smaller size based upon whether you like your garments to fit looser or tighter on top.

ONE BIG SIDE NOTE ABOUT OUR SIZING: if your boobs are bigger than a B cup in traditional bra sizing, then the difference between your chest circumference and your ribcage circumference is greater than 2". We have designed our bigger sized OOBRAs to accommodate for bigger boobs, but some girls have much smaller ribcage measurements than chest measurements. If this describes you and if you are right in between sizes, we recommend sizing down so that the elastic along the bottom fits nicely at your ribcage.

FABRIC: To create the most comfortable bra possible we picked out the softest fabric to go next to your skin. It’s made out of 46% cotton, 45% Modal, and 9% spandex for a perfect fit. Then, we added an inner layer of a special knit 100% poly to give our bra the coverage you want. What is Modal you ask? It’s a 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.

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.

We are happy to accept unworn and unwashed OOMBRAs within 14 days of receipt. If you want to return an OOMBRA, begin by going to our ONLINE RETURN CENTER and then mail it back to us at:
