You can find alot of nice clothes on ebay now a days. There are several items that are sold in lots and most often they are brand new clothes. I have purchased name brand / great priced clothing for my 5 year old son several times.
You will most likely find bettter deals for your 22 month old.
Good Luck. :-)
well if you look up GOTHIC clothing there can be many side tabs for 'emo styled' clothing.
i've got a few gothicy ones. but i'm not sure if you are a boy or girl so i just included them all
there are also LOADS of ebay stores:
http://stores.ebay.com/REFUSE-TO-BE-USUAL this is my favourite! scroll to the middle (i know its pink but they have some good stuff)
and it also depends on the type of 'emo' look you are going for.
