Hard to answer your questions without pictures.So I just recently purchased a pair of 'lightly' used N&F on eBay.
Named: Weirdguy 014113 Lightweight Selvedge.
Are these jeans supposed to be soft? Or are these jeans not 'lightly' used as described?
Also, the thigh isn't as loose as I expected, will they stretch?
How do you know when a pair of jeans have already been washed?
And also what sites are good to buy these from for? That have coupons eligible?
They're 10oz denim, so similar to Rigid Levis'. Definitely not "soft" like washed denim, but not "stiff" like 12-14oz.
Yes, thigh can stretch, but don't expect much.
Look up a few post. There's a pretty good deal on Naked and Famous at Karmaloop.com. Lots of different models for sub $100.
