Karlie Kloss's Trendy Bikini Is Bound to Make Someone Sing, "Loosen Up My Buttons, Babe"

Karlie Kloss joined her boyfriend, Joshua Kushner, and plenty of friends for a day of yachting in Capri, Italy. Karlie posed for some photos for Joshua, who generally takes the sweetest snaps of his girlfriend exploring. Karlie's bikini choice was unsurprisingly trendy, featuring a halter strap of buttons that trailed down her back and clipped onto the ivory bandeau top at the front. Her black, side-tie bottom was decidedly simple (a mix-and-match set, perhaps?). Karlie completed her breezy beach look with dark sunglasses, stud earrings, and a gold pendant necklace.
