Pretty much the reason why I'll probably never change my character gender (had a wish to play as female Roe), because I have almost all male-only outfits from Mog, so becoming a female character will move a significant amount of money to trash can. Though you still could use them on your retainers or squadrons, but... c'mon.

Thanks God that we at least can swap Seasonal gear on Calamity Salvager. I'm not sure if you can do it with "replica"s bought from Mog, though. Probably can as well? They should work the same.
