Skims - Waist Trainer - Onyx

"Usually waist trainers are rubber-based and so hard to get on," says Kim Kardashian, but this one by SKIMS is designed to sculpt and accentuate natural curves without feeling overly restrictive. It's made from ultra thin stretch-nylon and lined with the label's breathable 'power mesh' fabric. Kim likes to wear hers around the house or underneath a hoodie while running errands.
