Not to state the obvious, but model Gigi Hadid is seriously sexy. The older of the two stunning Hadid sisters can look insanely hot even while covered up [1] — though, of course, we also don't mind when her kick-ass body is on display. From her show-stopping jumpsuits to her teeny bikinis [2], Gigi's style is out of control [3], and her ensembles are only made sexier with her mile-long legs. Check out the gallery for Gigi's steamiest, most scandalous Instagram posts of all time, and you'll see that it's no wonder she has over 45 million followers.
