Grammy-winning singer Lizzo is launching a shapewear line called Yitty

The form-fitting bodysuits and undergarments that make up shapewear have become a lucrative business, with Spanx valued at $1.2 billion and Kim Kardashian's Skims brand propelling her to billionaire status. Now, singer and rapper Lizzo will enter the market next month with Yitty, her new venture offering bras, leggings, shorts and more.
