Just go to settings and go to profile than turn allow trusted skins

Is this only happening on a Dedicated Server, Featured Server, realms, multiplayer or singleplayer? 

Thank you for your report!
However, this issue is Invalid.

Unfortunately we don't accept issues related to External Servers here on the bug tracker, but please add more details if you think this also affects multiplayer over Realms, LAN, or XBL.

I'd suggest contacting the server owner directly or seeking help on the Minecraft forums.

It doesn’t happen on personal worlds or on any realms but I wasn’t thinking that it was the servers issue because it happens on all servers.
