When I bought this bodysuit and dress in July, I loved how comfortable, sexy and versatile they were. The problem I found however, was that I didn't have the proper bra to go with something with such a low back. I shopped around and tried a few products on the market. Here's my brief critique!
This low back bra is a viable option and a strong contender. The support is certainly there however this style loses brownie points in the "invisibility" category. The strap at the back limits how low of a dress or top you can wear. If the back dips lower than the bra, it will be noticeable.
Nubra offers a solution that I find works best for me. These cups pretty much have it all. They offer support (and this line has a new push-up cup), the adhesive actually stays on for hours (I've sweat in them in 30 degree heat with no problem!), and there are no straps at the back so you can go as low as you dare! Prices range on the Nubra, I got mine for $60 but it is worth the price tag and you get many wears out of it.
