When Gigi Hadid appeared on the Tommy Hilfiger catwalk in an itsy bitsy teenie weenie rainbow-colored knit bikini, well, the crowd went wild. Not that they weren’t already seduced by the Jamaican paradise Hilfiger had erected inside what looked like an airline hanger, complete with sand, water and even a tiki bar. Netted mesh tanks, patchwork striped sundresses and floral button-ups were all done in primary colors, adding to the party vibe. At the end, Hadid emerged again, leading a group of her fellow Victoria’s Secret buddies into the pool for a final lap.
