With the release of first cape, i want to remind Arena net about another cosmetic thats been asked before.
Undershirt slot. Primary function of which will be to cover up gear skins's open areas of character's body. This is old Reddit with example.
Seems to be simple and easy addition.
On personal note, i've been waiting for this a long time. This cosmetic addition will be primary way to deal with The Infamous Assassin's Coat on Female Humans. Too much open body areas there.
