OMG... One of the pairs I bought from UP smelt like plastic or something funky. It was actually quite strong. The jeans were the pocketless ones in a light blue wash. There wasn't a smell when I purchased them but after I got home, they smelt really strongly... They made other clothes in the same bag smell bad too (bought at different stores). I threw them in the wash and never wore them =S

Wondering where the smell was coming from as well...
