As countless under-dressed starlets have taught us over the years, it can be difficult to decide on a non-slutty balance of covered-up versus skin out. Luckily, the new sheer and semi-sheer options popping up all over make it easier to find the happy medium and look sexy in a covered-up sort of way. This blouse, for example, could definitely be worn tucked into a pencil skirt with a tank instead of a bra for a chic, appropriate look. [$31, Asos]
