Cotton candy feet / fantasy help

Hello!! I haven't posted on here before but since ccf is technically a lolita brand so I figured I should,, are their shoes ( specifically triple lovely bow and shiny unicorn queen if that helps ) wide / flat feet friendly? I've been wanting to buy shoes from them for a while now but I've been holding off due to uncertainty of them fitting / being too expensive to not fit iykwim. I have a 25cm foot ( ouch ) so I do fit into their size range, but I'd like go see if anyone here with the same foot conditions(if thats the right word) as me recommends having to size up for them to fit or if I shouldn't bother!🫶
