These pants are wonderful if you like a snug-but-not-super-tight fit with a substantial fabric. They are not at all see-through--even the white. They are made out of a sort of french terrycloth, so there's a tiny bit of texture on the inside but they are smooth on the outside. They are NOT denim. These said they have "butt-lifting" technology but I didn't experience anything like that in the three pair that I purchased. They are low-waisted and about 32" in length which works perfectly for my leggy/shortwaisted 5'7" frame. THEY RUN SMALL. I couldn't figure out what size to order so I contacted the seller (very nice BTW). I usually wear an 8-10 and I'm 137 lbs.--she told me to order the XL. I was shocked but I did it and they fit perfectly. And the seller said in her email to me that I could just send them back for a refund if they didn't fit. They wash well but I wouldn't put them in the dryer--too much risk of shrinkage. I've gotten lots of compliments on these skinnies whenever I wear them. I also purchased the 1119 style in Khaki (which is really camel-colored) and they are pretty much the same pant--a little different styling and $10 more.
I notice that although they fit well, they tend to creep down, a problem I have fixed by wearing a wide belt through the belt loops with them....Which means I often am wearing two belts at once, but, hey, at least my pants aren't falling down.  I don't think a size smaller would correct this.
