Noticing an abundance of your pals wearing fun new flips? Odds aren't too shabby that they're Havaianas, the popular flip-flops that have been around since the '60s.
Known for the line's range of creative, sometimes exuberant designs, the shoes were originally inspired by the Zori, a Japanese sandal made with fabric stras and rice straw soles. Havaianas and its parent company also donate a portion of profits to environmental and socially responsible nonprofs like Conservation International, which you can read more about here.
Available at the Dressing Room and Barneys.
