the motion leggings are the first tights I've ever bought worn that actually stay on, don't slip, squat proof and contouring. If you don't have a pair of these, do yourself a favour and just do it because they're amazing! Especially when you match them with the mid rise crop singlets :D. They are also a thicker material that keeps you warm but not uncomfortable when working out so I use these leggings for the days I train and also for outfits to lounge in, super comfortable!
