If you're Olivia Palermo then you get to vacation on not just any yacht, but designer Valentino's glamorous yacht. The socialite took to the seas wearing this Violet Lake slate bikini top ($87) with matching bottoms ($87). We particularly adore the unique u-shape detail in the middle of the bikini bandeau top, giving it a sexy feel. Olivia also sported black cat-eye sunglasses to shield her eyes from the sun, then later covered up in a printed off-the-shoulder dress. Score her exact bikini now, then top it with this French Connection printed smock dress ($77) and throw on these Mango cat-eye shades ($30) to get Olivia's chic high-seas look.
