T- shirt bras are a top drawer staple for good reasons. Their smoothing and seamless design features keep them hidden beneath t-shirts so you never have to worry about visible bra lines again. In this guide, we’ll discuss everything you need to know about t-shirt bras and point you towards some of our best picks.
What is a T-shirt bra?
A t-shirt bra is a type of bra specially designed to remain invisible beneath t-shirts and other clothing items. They have seamless, molded cups and smooth lines, which keep them from showing through shirts.
How should a T-shirt bra fit?
It should fit about the same as any other bra you would wear. The bra should feel supportive, fit snugly but not tightly, and be comfortable to wear for long hours. To ensure you get the best-fitting T-shirt possible, try on a few different sizes and styles, and make sure you get your correct bra size.
