Though you may be covered up, a paper-thin tee still presents some challenges in terms of modesty, especially when it comes to what bra you're supposed to wear them with. A regular underwire bra can feel a bit to revealing, but we love how chic a fashion-forward sports bra looks underneath a thin tee. Not into showing that much skin? A skin-tight black camisole can also do the trick.
