How It Works
How It Works
All RUBIES bottoms are meant to be worn comfortably. Not too tight or too loose. It is recommended to use the size guide to get the right fit.
Unlike conventional tucking bottoms, RUBIES are not intended to completely "hide the bump". Instead our advanced design converts the pointy area to a more feminine mound. This is why they are extremely comfortable compared to any other products on the market.

All RUBIES tops including underwear and swimwear are designed for people with minimal bust development. They all have pockets to accommodate padding.
Our bras are perfect for first-time wearers and can be fastened with the clasp or slipped on over the head thanks to their stretch.
