You wouldn't think that a pair of leggings meant to lift, support, and smooth would be pleasant to wear. But damn, the Spanx Active Booty Boost High-Rise Stretch-Jersey Leggings (£88) turned out to be so comfortable, we were fine wearing them around the house for nearly eight hours. For one, the fabric is ridiculously soft and has enough stretch to it to not make the leggings constricting. Secondly, the high waist is so high, that it doesn't pinch; in fact, it feels nice and supportive around your abs, waist, and back (although, we did find it rolls down every-so-slightly during Pilates mat classes). And to add to the long list of why we like these leggings: yup, they're 100 percent squat-proof.
