Selling things

I have a couple small bags of dresses (probably around 10 items in total) in size Small (roughly size 2-4) that I wore in college or high school and no longer fit me. Most were probably manufactured in the 90's, and are little cocktail dresses in black or flowery silken stuff; one is a vintage flapper dress. I want to sell them if possible.

I'm looking for recommendations on whether to use eBay, Craigslist, or something else, and recommendations on how to build the ads (I'm planning to list the items separately). I'd like them to sell the first time (especially on eBay since they charge per ad), I don't care too much about what price they sell for since my other option is donate them and not get any money, I'll be charging shipping if it's not a local pickup, I want to get my money before mailing/delivering the items. So, thoughts/advice?
