Designer brands, clothing in excellent condition. I got a light olive green suede jacket, with beautiful buttons (with tags still attached) for $15. I have gotten so many compliments for it as well as for other clothing from swap.com.
Once, I bought new baby clothing that was gorgeous and originally expensive at prices that were SO affordable I couldn't believe it.
I like that on the site you can specify not only the size, color and style of items you want to be shown, but also condition in categories like "new with tags", "like new",
"very good", etc.
The one time I had to return a few items that didn't look well on, swap.com made the process extremely easy. The return label was emailed to me and full price was refunded.
It also makes a difference to me that I can use Paypal for payment and don't need to disclose any credit card information.
This is my favorite clothing online shopping site!
