This is a staple when you are pregnant. I bought a few of these and wore them daily with all of my dresses throughout my pregnancy. The material is nice and stretchy and the color is the perfect nude. I love that the bottom of the item does not show through at all. Completely invisible.

I include these on my "must-have" maternity list, especially if pregnant during the spring/summer. The material over the belly is very thin, but acts as a barrier between a sensitive belly button and clothes. It also works to hold your stretch mark cream on your skin instead of clothes. The structure provides a slight lift and supports your growing belly. Plus, it keeps your tush an thighs looking their best. These are super comfortable and a wonderful undergarment to keep everything where it is supposed to be.

I ordered M even though I was border line between M & L given by pregnancy size and it was perfect.

These are great for mommas who want to feel tucked in and smooth. I wore under a very clingy blush dress and it smoothed me out and me feel confident to wear something more revealing.

This item ripped in the belly area after only 2 uses. I was very careful with how i washed this item however the fabric that goes over the belly is not great quality and i got a hole in it :( such a shame.

I normally hate shapewear. I feel like it's a necessary evil for some outfits; however, I love the Power Mama shaper! Super comfortable and breathable. something that's so necessary when pregnant! It felt like they gave me added back and belly support. Love them!

I wasn't expect too much when i order this maternity shaper, there isn't much to shape my lower body to be honest at wk 33. I simply think this can work as an extra support to my belly. So it turns out, it supports my melon sized belly comfortably, the texture is light and breathy, i wear it without any problem under my leggings. As to the shaping part, surprisingly, my rear end look firmer and slightly rounder when i check myself in the mirror. I should have bought two pairs of it!

Lived in these during my pregnancy, the extra support (although not much) felt nice was great from when popped out of normal stuff about 18 weeks.
