I have bought a cashmere sweater (had cigarette smoke smell) and a pair of Guess shorts (for a dollar - plus shipping) on Ebay. Also numerous clothes for my kids. I wouldn't buy shorts or paints unless it's a brand I have worn and know the size.
I normally don't like buying just one item, but like "lots" of clothes in the same size - easier to find with kids clothes. I like pictures, even if they are a bit fuzzy.
I hate all the listings of underwear and junk stuff sold by dealers and wish there was a way to weed those out. There are so many pages of clothing that it's really daunting to go through unless you are looking for something specific to put in a search, ie. Burberry jacket.
