Great elasticity and nice fit. The roll a little but it actually looks sexy. If you don’t like the roll down, add garter belt for ultimate sex appealMy only issue is personal and not a defect. I love them and will reorder soon.I am a 1X. I ordered these and they just don't fit! The description says plus size but they are WAY SMALL. I had to stretch out forcefully just to get them over the knee. Not a satisfied customer.These were not all what I was expecting. I don't see how they could fit a person up to 250 pounds, as they barely stretch enough to fit on my 170 pound body. Runs very small. And not really opaque at all when stretched at all. The quality was lacking for the price as well. Seemed comparable to what you would expect from a cheapo Halloween costume pair of thigh high's that would be half the price or less. Returning, and at least the return process seems easy enough.I bought these for my company holiday party. They do not have the silicone on the inside of the top. They were falling down within 15 minutes. They spent the evening in my purse.They fit me! I'm a size 20 and they fit. They are long enough to reach my garter and then some.I have thin legs and these were a little tight.Having no elastic/silicone at the top to keep them from sliding is quite bothersome and they can't go very high without the risk of rolling down. For reference, I am 6' 1" 250 lbs, but I have pretty standard width legs.The item is really sexy as I wanted. The item and seller are recommended. Thanks.
