I generally love Spanx products in general--I have the open-bust bodysuit and it's pretty awesome. I'm excited about these reversible tights, they're double-duty and nice and thick for the winter months. But by the size chart, I am right in the middle of the "C"s, but I find these tights to be quite a bit too big, certainly much too long, and I'm decently tall at 5' 8". But even so the waistband still cuts uncomfortably into my waist! (And I'm not big around the middle, if anything, I'm "pear shaped." I've already worn these a few times, so I can't return them for a B size, but I would be interested to see how a smaller size fits. Maybe one day I'll spring for a second pair in a different size and see if that helps! I do think they are good quality tights and I continue to wear them a few times every week, but the fit for me is weird.
