Designed by a pediatrician who’s written multiple books on puberty and a mom in search of a well-fitting bra for her preteen daughter, the OOMBRA solves many issues associated with traditional training bras. First off, it’s made of a buttery-soft jersey that feels like nothing on, with zero hardware, uncomfortable bands, or awkward padding. It has a patented center panel that gently compresses without binding. Best of all, it’s meant to support girls as they grow (OOMBRA is suitable for barely there breasts up to size 34D or 36B). Oh, and did we mention it’s reversible?

• OOMBRAs use a simple single-measure system to fit a wide variety of body shapes. 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 between sizes, go bigger.
