Sofia Richie is making the most of the summer, hanging out with pals on the beach in Malibu. The 21-year-old was spotted on August 8 rocking a white string bikini and a pair of unbuttoned light wash jeans. The blonde beauty flaunted her taut abs while strolling along the shore in black sunglasses with a glass of wine in hand. She pulled her tresses back into a messy bun, and accessorized with gold necklaces.
