I bought this during my third pregnancy because my friend swore by it's comfort and ability to alleve back pain. I purchased it at Target for around $25.
I purchased the white Maternity Belly Bra, but there is also a nude color and black color available. There are four different sizes ranging from small to XXlarge, depending on your bust size.
I honestly thought this would be an awesome product and at first, it was good. It is made out of a nylon material primarily, but does have some spandex in it as well. There is a bra built right into it; however, I found the bra to be a little bit itchy. Also, the thick shoulder straps made it impossible to wear some shirts because you could see the straps.
One pro about this product is that you can just throw it in the washer and dryer. I would never purchase another one of these because honestly, it didn't really alleve my back pain at all and it was not the most comfortable thing to wear, especially in the summer in your third trimester. Need I say more?
