Hey! Just wondering if this is intended or a bug or w/e.

I bought a Halloween Costume to apply to my sub male (here) but when I got to equip it he doesn't show up on the list. First I thought maybe it just wouldn't stack with the tiger's eye, but when I equipped the tiger's eye to my main male he still showed up on the list for it to be equipped.

Am I missing something that's not letting me equip it (extremely possible, as I tend to Easily Miss Things) or do you think this is a bug?

Thanks!
