I'm super tall and heavy, so I bought my usual XXL size, and it was not what most tight-makers would call XXL.  It was maybe, maybe XL.  Maybe.  I tried stretching it out, and then pulling up, and it snagged just like a regular pair of tights.  Darn it!

That said, I believe these are ballet tights, and generally dancers are pretty svelte and shortish, so I guess in the ballet world an XXL is a different size scale.

The nude color (technicall "light suntan") would have been great to wear at work, without worrying so much about snags.  Would be especially good for people with something to hide on their legs (not shaved, spider or varicose veins, bruises, cuts, etc), while still looking like normal legs, or like pantyhose.

Just size down a bit if you are not actually a dancer.
