Aeria Games just implemented the in-game item mall. While it only sells 7-day costumes at the moment, it gives you the opportunity to try costumes on before you buy. So suppose you wanted to see if a ninja costume would look good on you - click on the $ button on your menu in the bottom right corner of your screen and it on. Then, if you're satisfied, you can buy the permanent version on the online item mall! I hope this helped!
