Here are some cosmetic ideas if anyone wants to use them and make them on the workshop.

A green army man cosmetic loadout for Soldier... You know those little green army men kids used to play with? This cosmetic set would be a green hat, green chest piece, and green pants, making Soldier look like the army man toy.

Blue pants for Scout. Since Valve removed them so fast, even though lots of people liked the change.. I think it would be cool if there was a cosmetic that was just the same blue pants for Scout, so it can still be in the game in the form of a new cosmetic.
