Skins glitch where everyone is steve and alex

Put the summary of the bug you're having here

I was going on Minecraft and everyone was supposed to look the same.
What actually happened was everyone showed up as steve and alex for me. I asked other players they said i looked the same and they saw everything fine. For me even heads are steve. This bug only takes place when i go into 1.9 and when i go into any previous version its fine. Please Help!!!
