The Gentleman’s Attire achievement is unlocked by completing the "Skin It To Win It" challenge. Wait I just realized that I was told wrong.
It was for the community completing the Skin It To Wit It challenge I believe but since that has been done now it unlocks in the Singleplayer without having to do anything.
