Everyone! The lovely capri tights are indeed from Target! They are $6 nowadays (which...hmph), though at my local store they had a few in the clearance bin in fun colors (which I may have purchased. Because aqua capri tights are totally dress-code).
The leg opening has similar construction. I wear them just under my knees, but they would stretch down to mid-calf. The leg opening isn't too snug either, so if you have muscular calves (which I bet you do if you're a dancer), you won't feel like they're cutting off your circulation.
They are not opaque, though not totally sheer either. I would actually feel pretty comfortable wearing them over my leotard without a skirt. But they are definitely NOT like leggings.
In short? If you like to wear capri tights to class, you should swing by your nearest Target and pick yourself up a few pairs of these. At $6, you really can't go wrong.
