I bought the outfit at the shop, how do I equip it?
I don't remember the default keys but they added 2 additional keys (button 5 and 6) specifically for menus to change pages. In the shop you can press those to access the gacha machine, which doesn't work, as well as the outfits for Jasmine. If you want to unlock the topless and pierced nipples outfit you need to get Jasmine's picture, go into the extras and then the gallery, select her image, and then use button 6 to zoom in all the way on her tits, it should unlock automatically. It changes her dialogue to reflect her topless nature by saying shit like "No, you cant feel the "merchandise" and such.
