The Favorite T-Shirt Bra vs ThirdLove 24/7 Classic T-Shirt Bra

The ThirdLove 24/7 Classic is the safer pick for most shoppers: it runs A to G with + and ++ cup options and XS to 3X sizing, has built-in foam cups for nipple coverage, and can be machine washed. The Favorite T-Shirt Bra is the one to pick if you need an H or I cup, since ThirdLove stops at G. Both are seamless microfiber T-shirt bras with adjustable straps. Owners of the ThirdLove rate its smooth, cool fabric and true-to-size fit; the Favorite's stretch microfiber and cross-back conversion suit larger-band, fuller-cup wearers who want underwire support.

• Choose the Favorite T-Shirt Bra if you wear an H or I cup, want underwire support, or want straps that convert to cross-back.
• Choose the ThirdLove 24/7 Classic if you fall in A to G, want wireless comfort with foam cups, or prefer a bra you can machine wash.
