Hi, I would like advice
And maybe some suggestions for what to put on the bottom or how to change my dress, the cheapest possible. Thanks.

Hm... You could always get that black wasp (the corset thing that my current avatar has on) That should help get some black around the middle there on your avatar. =)

the purple of dress is really not matching with the rest of purples
so i suggest getting more of that purple items..socks or something
and yes you do need a belt^^
