Ok so

at lvl 15

you get a free 7 day costume, basically clothing that will actually look different from what you always wear

lvl 24

now you get a new 7 day costume that comes with wings

lvl 32

you get no new costume, you get a bandage as a face changing thing
earing and 2 rings

no costume   

the only original one here is Undelos with her vampire..

I'm guessing its different for us warriors, I mean the winged costume along with the rings and all, for some reason I really want a winged costume, but a little more... you know... manly man like.
