Unless your clothes are all name brand and worth a decent amount, in my opinion it won't be worth your time and effort to do eBay. I'm a powerseller on ebay so I am definitely supportive of selling there when appropriate, but I have given up on selling already worn clothing there. You have to describe the item perfectly, and then even when you think you have there will be buyers with tons and tons more questions about the sizing and fit. You also need to take plenty of pictures. And then you run the risk of it not fitting when they get it, etc. And you end up making probably less than $5 per item (if that) after fees and everything, and just the fact that used clothing doesn't sell for a lot usually.
Where you probably would have some luck is on facebook, if you have a facebook account. Most cities have quite a few garage sale or swap groups. In my area they are almost all called swap shop or swap & shop. Just get on and start searching terms like that and you'll find groups around you. I have sold quite a few things that way actually - clothes, bedding, shoes, etc - things that wouldn't be worth my time on ebay.
