These leggings have become my weekend "uniform."  They are not see-through at all, and they're super comfy.  I'm 5'6" or 5'6" and they go down all the way to my ankle.  I read some reviews of people complaining that they are too high-waisted and I can definitely understand the complaint if you prefer low-rise pants.  However, no one will generally see the waistband of your leggings, so I don't think that's a big deal.  In fact, I really love the fact that they are high-waisted.... as a larger girl, it makes me feel much more comfortable and kind of doubles as leggings AND Spanx for me!  They really smooth out my tummy area and I have no problem wearing them with oversized sweaters or button-ups with boots.  After wearing a little while, they tend to sag a bit in the crotch area, but I think that's true of all leggings.  Just pull them up every once in a while, and you'll be fine. :)  For reference, I'm 190 pounds and a size 12, carrying most of my weight around my middle. Love these!
