We have it too, and my partner loves how it hides her lower body. I absolutely love a “mummy tummy” but she finds this a huge boost of confidence and it’s also really comfortable during sex. It quite easy to kind of roll up and stretchy to spread your legs quite easy 👍🏻
I’ve been considering getting that too. The other think I like to wear (I have a elephant tummy never mind mummy tummy 😢) are the body stockings. They are great as they do mini dresses too.
