It's very rare that we spot Olivia Palermo in a bikini. In fact, we can't even the remember the last time we saw her in one — especially without one of her trademark breezy cover-ups [1] and preppy straw hats. Olivia shocked us all by wearing a sexy burgundy bikini that instantly fogged up our computer screens. The starlet showed off her toned physique in the wine-coloured two-piece by Solid & Striped while lounging on a pool chair in Mustique Island.

After getting over the initial shock factor (did you know she had a dainty butterfly bellybutton piercing?!), we zoomed in to admire her red-hot bikini. Olivia's flattering top featured belted straps, and she accessorised her beach-ready look [2] with oversize sunglasses. Read on to get a closer look at her sultry swimsuit snap and buy similar styles if you're feeling inspired.
