Alix Earle, Katie Austin and Jena Sims Koepka turned a hot day in Miami on Friday into an absolute scorcher ... leaving little to the imagination in some barely there bathing suits.
The models/influencers hit up the W South Beach for yet another steamy Sports Illustrated Swimsuit party ... and they looked amazing in tiny bikinis.
Earle went with a classic all-black look, while Austin donned an olive two-piece for the occasion. Meanwhile, Sims -- the wife of golf star Brooks Koepka -- was more adventurous, opting for a fun life-saver-themed sheer top and some red bottoms.
