Back in April, Britney Spears topped this floral Tibi dress off with her signature straw cowboy hat and matching boots while coming out of her dance studio. Just last week Katherine Heigl gave the same summer frock a feminine touch with strappy flat sandals and a delicate drop necklace on the set of her new movie, 27 Dresses. We love this Tibi dress, but unfortunately the older style is no longer in stores. Get the updated Luau floral dress, on sale $160 from $319, at net-a-porter.com. Tell us: Who do you think wears the Tibi dress better–Britney Spears or Katherine Heigl?
