I've just received a top which I won on eBay.
It's a size 18 but is absolutely tiny! I'm not just in denial about being three sizes bigger than I think I am...sometimes 18 clothes fit fine, sometimes they're too small, sometimes they're too big but this is much, much smaller. If I were to relist it (which is probably the most likely outcome) I'd have to list it in a smaller size because I can't see it fit any size 18.
I'm wondering if it's worth contacting the seller to see if they'll let me return it or whether it's just the risk you take when you buy clothes off eBay.
I've also just received a skirt which is also an 18 and rather loose but the liningmis all ripped
