Soft Clean White is 97% cotton. 3% elastane. Not as soft feeling as other 711s I have in other colors with different fabric content. I am 5'7"  and about 140lbs, and usually the size 29 in 711 fit me perfectly, so I ordered 29 in the white. Technically, they 'fit'. Not too tight, but fitted. Stretchy enough that they don't cause the dreaded muffin top. The white is thick enough that they are not see-through at all. I would have LOVED to keep them, especially since it can be tough to find white jeans this time of the year(believe it or not), but the left leg is noticeably tighter and literally smaller than the right leg. I even got my measuring tape out to prove to myself that it's not just my imagination... This is the 3rd time I've bought 711 Levi's and although they seem ok when you first put them on, when I move at all, is when I notice the irregularity. (One of them I actually purchased from a B&M store, and did exchange for a perfect size 29). I don't know what's going on with Levi's, and maybe one of their factories is just not up to par, but this kind of irregular product should be considered defective. I really wish I didn't have to return these, but they are just unacceptable. Now the price, since I first purchased these, has gone up(annoying!), so I don't know if I'll bother trying another pair. Maybe if the price goes down, and if they are available. Good luck! If you get lucky, these jeans are great! I love my other ones.
