What is a T-Shirt Bra?

A t-shirt bra is typically a kind of seamless, molded cup bra. The cups are designed to not show any lumps, bumps, or textures through your clothing — even when worn under the most form-fitting t-shirt or tee. T-shirt bras are popular not just for wearing with tight t-shirts, but for the seamlessness and versatility of wearing with any garment in your wardrobe.
