They are fish net hoses. I would think by them being for dance they would be a little more durable. But they are easy to get a hole. My daughter needed them for dance. I have purchased 4 pairs in addition to the 3 she got from the dance sponsor. So she went through 3 pairs the first 3 games of football season.
Please note that these tights are advertised with a "MOCK" back seam. It is not a true seam! It is just some heavier stitching in the back and doesn't look like regular seamed fishnets. The low price is attractive but 3 of my students had holes in them after just putting them on the first time.
