What is a t-shirt bra?

A t-shirt bra is a bra with naturally rounded cups that are made of smooth fabric. T-shirt bras are invisible under a t-shirt, supporting the breasts without seams or lace details showing.

How do you wear a white t-shirt without your bra showing?

If you don’t want your bra to show under a white t-shirt, wear a nude-coloured t-shirt bra that matches your skin tone.
