Gurrrl, if you don't take sunglasses you're a stupid thang.
I'll probably take a pair of cat-eyes even though I think they make my face look weird. Whatever, they're so fun!
It's probably not a good idea to take the most expensive pair of sunglasses you own, as they might go missing/get trampled on.
PS. Remember the SPF, a sunglass tan is never kewt
