The good news is, all these ladies have completely different face shapes, proving that the addition works on most everyone 鈥 stick to the actual frame shapes that work best for your face. Try pairing them with your next 鈥70s-inspired ensemble, or even with just jeans, a tee and kicks on the weekend to get a pretty easy celeb-approved style update.
