Color is fantastic. Very naked feeling. Runs big. I’m a size 12/14 and usually wear XL with them sometimes feeling tight. I am pear shaped - 35” waist, 47” hip and these fit but were quite loose in the waist. I might consider sizing down if I wanted to tighter. They would be very a bump-friendly non-maternity option
