Summer doesn't officially start until June 21, but that doesn't mean you shouldn't get a head start on sunny essentials. Since FitSugar can school you on sun protection, we'll focus on the clothes. Luckily, one of our favorite Summer sites, Roxy, is currently hosting a superb sale. Select swimwear, dresses, hats, and accessories are marked up to 50 percent off. I think it's time for me to jump on this festival chic Gladsom Dress ($27, originally $40).
