NB: As someone who'd never worn thigh highs before getting these (and hasn't really bothered trying more pairs), I'm not entirely sure how much of this is specific to these thigh highs versus common to all thigh highs, but I'll do my best to be as specific as I can.

The first thing I noticed about these, which I'm sure is a common first-time-wearing-thigh-highs experience, is that they look nothing like in the photo. (What did I expect? I don't really know.) Yeah, most of us have fat on our thighs, who knew! I was mildly disappointed, but it's really not a big deal. They do look cute, although the lace tends to bunch up at the top and it can be difficult to smooth out. They also slide down somewhat easily, but I don't know that you'll find any non-garter stockings that don’t. As far as these things go, they're as comfortable as something that squeezes the tops of thighs to stay on can be. The first time I wore these in public was to my first time at a BDSM club, and I felt awesome enough that I didn't mind having to periodically yank them back up and re-straighten the backseam (that's another thing—how on earth does anyone get backseams to align right in the first place, let alone keep them that way???).

I admit I've never been particularly good with keeping hosiery in shape, but these did start getting runs rather sooner than I expected (after only one wearing!). I wouldn't recommend throwing them in the wash; they're delicate enough that if they snag on something they're done for. They can be quite fun to wear in bed, although beware of fingernails or toenails catching on them. (Same goes for putting them on; roll them on rather than pulling.) These are definitely good if you plan on wearing them just for a night or maybe a couple times for short periods (and they're cheap enough that you don't have to feel bad about doing that). I'd look elsewhere if you want something a bit more durable.
