Alessandra Ambrosio was beachy perfection, rocking a colorful OndadeMar triangle bikini ($182), white denim cutoffs, and white Wildfox Couture shades ($210) in Malibu over the weekend. The model mom accessorized her bold bikini with drop earrings, a double wrap necklace, and orange nail polish. Work her exact teeny two-piece and exact sunglasses with these white distressed denim cutoffs by Citizens of Humanity ($158) for a day at the beach, then layer on a neon tank for lunch at the local bar and grill.
