What a second slot I think could b added is one with head masks, like a lower face mask or second face vanity, items that could already fit into this category would be vans like the half gas masks, cat ears, devil horns, etc, basically small vans that could b placed on top of others. But with some van masks that cover you’re entire face, would be not allowed to put on a 2nd one or so, because, well it’s a mask and it’d prob just look weird, so imagine like scorn with devil horns, or xray with Apple, heart visors with a lower gas mask etc
