Uhmmm, lol. Best way to buy Nx on girls is for them to just like wear all the stuff they want to buy in CS. Then under the screen that shows your character wearing the items you wish to buy there's three options/tab things. You click the "Buy Equipped Items" one. Bam! Then you should have your clothes that you want. -cough- Don't ask me how I know... I just know dammit! D:
