>>2703777If you're a newer player, I would suggest saving the trash-level suits to use as upgrade materials for suits or accessories that you actually use. You could also exchange them for VIP points (not coins, those are different) and trade those points for Zack Bucks if you're running low.
The only reason I suggested upgrading trash suits was because I thought you had an extreme excess of Zack Bucks that you needed to get rid of (there is a cap on how much Zack Bucks you can carry that some veteran players have complained about), and sought a solution; otherwise, there is literally no reason to ever upgrade trash suits.
