Well it really all depends on how much you're willing to save up for and what kind of look you're going for. You can get many different articles of clothing from Hot Gossip and (although each store has rising prices the further you look into them) it is one of the more cheaper stores. You're definitely going to need socks and shoes, those you can get from Hopscotch at decent prices.
If you do not know what kind of look you want to go for, then download the MAC (Menewsha Avatar Creator) and come up with a look. It also gives you the prices of the items you choose in the "file" part of the menu.
Hope my advice helped a little, I'm not necessarily the fashion expert of menewsha. ^^;
If you need to know anything else, just ask :)
