Sofia Richie is having the time of her life on her holiday family vacation to St. Barts. We are pretty much living vicariously through her Instagram photos and videos, from a luxurious yacht to fun activities like jet skiing and snorkeling. Sofia posted a photo of her snorkeling adventure, wearing Frankies Bikinis' Tia Set - a simple triangle side tie bikini in a delicate pink floral print. The style has been a best seller and has been worn by Sofia on multiple occasions in a variety of different prints. Check out Sofia's seriously sexy bikini snaps from this trip and more on US Weekly!
