I been having this problem ever since I got Minecraft (I got it around may 12th is when I got it) and every time I'm in multiplayer or by my self i only see Alex skin or Steve skin for every character. I tried to re installing or leaving it alone as well as downloading a second one to repair but the items i have done doesn't seem to work .(i as well have allowed skin on so i don't see what else could it be).
