I have a pair of medium Assos bib shorts for sale, fantastic condition, bought last year for a trip to Paris. Always washed in the genuine Assos bag, with gentle detergent.
Only the slightest of wear to the crotch, you would really have to look for it, but just being honest.
Cost £116.99 here http://www.evanscycles.com/products/assos/fi-uno-s5-bib-short-ec017706
Great shorts check the reviews, wouldn't use any other short now, only selling as they are too small and I now have a large pair!
