Do they have any distressing or anything on the front?
Also, I've been wanting to get a cement-colored jean for a while- but I'm 6'6. The closest I can find is
But it has like ~~6% Polyester, 2% Elastane.
The last time I bought a pair of jeans with elastic (2% Spandex Gap jeans) they bulked out like two sizes when I wore them. How much would 8% go?
The 6% polyester won't make them stretch! just the 2% Lycra, so you don't need to worry.
My purple face are 5% stretch but they always shrink back when washed, although my Naked and a Famous just seem to get bigger with washing unfortunately...
Hope this helps:)
