Editor’s note: The following is a guest post written by Rachel Zoe, stylist, fashion designer, and creator of The Zoe Report. This week Rachel dishes about her favorite accessory.

In terms of fashion meeting function, there is no accessory more crucial than a standout pair of sunnies . . . or do not disturb signs, as I like to call them. They put the finishing touch on an outfit while protecting your eyes from the sun or concealing puffiness from a late night out (we’ve all been there). When shopping for a new pair, pay attention to the shape so you choose something that flatters your face AND color — I almost always suggest neutrals since sunglasses are something you will wear every day. Also, keep in mind that you do not have to spend a fortune to get a-mah-zing sunnies. True, it is great to have at least one very nice pair — Oliver Peoples Balmain 2 Aviators are my ultimate fantasy — but there are countless stylish options out there with savvy price tags. For inspiration on a few different styles at a variety of prices, read on and see my current top five do not disturb sign picks . . . ! xoRZ
