I'm honestly highly against this. Since /outfit is nice for those who already "own" the clothes realistically.
But it would be nice to see an increase in outfit slots, but other than that I'm going to throw up a -1 for this as it's generally a low priority when the developers are busy with other things, plus a lot of people wouldn't want it changed. Maybe allow this and also keep the current outfit system to make both sides happy, as I know a lot of people personally who'd be highly against this.
