Contrary to the description and to the picture on the cover, the control top has a faintly visible dividing line between the panty and the leg itself.  It's not nearly as dark and noticeable as other control top hosiery, so I'm fine with a light line, but if you're looking for a true sheer to waist look, this isn't it.  The line is higher on most, so they'd probably still be fine to wear with a short skirt or shorts if that's your sort of thing.

otherwise the appearance is very shiny sheer, they're also very smooth and durable, with no bagging. They do tend to run a bit small, so whatever size you think is appropriate you may want to go up a size just to make sure.
