If you're a trans woman, on the transfeminine spectrum, or someone assigned male at birth who is looking to create a smoother profile in the genital area, Rubies shaping underwear will give support in all the right places, with no tucking required.

Rubies are made from the highest quality compression spandex and mesh, providing a comfortable and secure fit. This bikini is slick, stylish, and sensible.  

Designed to be worn as swimwear, the Bikini Bottom can also serve as everyday shaping underwear. Rubies Bikini Bottom offers a bit more control and compression than Rubies AJ Cotton shaping underwear.

The Rubies Bikini Bottom is meant to be worn comfortably-- not too tight or too loose. It is recommended to use the size guide below to get the right fit.

How it works
RUBIES helps you embrace your feminine form by reshaping. No tucking. No tight compression. No two sizes too small. No thick padding. No distracting patterns. Just great fitting, super comfortable clothing made specifically for trans women that look, wear and feel like regular underwear and swimwear.

Unlike conventional tucking bottoms, RUBIES are not intended to completely "hide the bump." Instead, their advanced design converts the pointy area to a more feminine mound. Two layers of compression mesh pull everything in, and an inside panel/gusset adds extra strength.

Sizing for RUBIES AJ adult bottoms should be close to standard US Women's sizing. Measure all the way around the waist just under the belly button. Pick the size based on which waist range it fits in.

To keep your RUBIES feeling comfortable and keeping their shape: wash cold on gentle with mild detergent. Avoid bleach and fabric softeners. Lay flat or hang dry and skip the dryer to protect the fabric stretch. Do not iron.
