Bought the 2 pack. They keep my tummy in, and they fit me well as a taller lady. I normally would wear an XL but bought the 2X to accomodate my height a bit better. I would think something called "Super Opaque" would be...opaque. They were a tiny bit see through, which I was slightly disappointed by, but I'll keep 'em and wear them anyway since they're great otherwise.
