First, just because she looks amazing, let's talk about the amazingness that is Nicole Richie just casually strolling the beach in St. Bart's looking amazing.
The best part: to get that look, all you need are a black bikini, a white hat, and some big sunglasses (Nicole is wearing a House of Harlow pair that is the only item I have ever put myself on a waitlist for...and is also the only item I have ever taken myself off of a waitlist for, because I felt silly). You don't even need to do anything with your hair or wear makeup; the hat and sunglasses take care of those little issues for you.
