Haviana flip flops are a summer must-have for any girl. Try a fun color like hot pink and you'll be surprised how much it grows on you. And at $15 a pair, you can afford the neutrals too.
I went to Sydney, Australia last year and like an idiot, the only shoes I brought along were the heels I walk from cab to cab wearing in NYC. Big mistake, as my Sydney friends thought nothing of walking home every night for half an hour. By the third day, I had overcome my fear of flip-flops ("They just leave your feet so exposed") and confiscated a pair of Havaianas from one of my friends. The rest is history. These are the greatest flip-flops ever, and they look cute with everything. I wore them with jeans, shorts and tube dresses. Oddly enough, it always matched. Plus, Havaianas come in pretty much every color known to man.
Havianas are my go-to shoe for the beach.
