No, no, no -- they weren't day drinking! Kendall Jenner and Hailey Baldwin hit up Wasteland vintage boutique in LA on Saturday and from the looks of these pix, we don't think they need any fancy clothes at all -- just show us those legs for miles, girls!

The supermodel duo strutted their stuff in jeans (Kendall) and cut-offs (Hailey) and strutted their stuff for photographers, looking every bit the successful models they are. Ahhh, to have the body of a teenage model!
