SKIMS Stretch 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.
