I just got these in the mail today and had to try them right away, so make sure to read this review knowing that I haven't taken a chance to break them in or test their durability in a washing machine. First impression says they're very light and soft, like a typical pair of tights.
The material is thicker and smoother on the black portions of the tights, as expected. The transparent portion is very soft and stretchy, with a slight slippery texture when you pull them on. The cat face is the same color as the "nude" portion of the tights as well, not white. But it doesn't stretch and vanish, so that shouldn't be an issue.
Unlike in the pictures, the cat face only comes up to just under the knee on my legs (I'm 5'3" and very leggy) unless I stretch the material more, which makes the black portion of the tights more transparent than I would prefer. But even with that, they're extremely cute and make a great accent piece for any skirt ensemble.
Maybe after a wash or two the material will loosen up, but for such a low price I have to say these are well worth it.
