The moment of epiphany – when, after hours of work, a physics problem seems to resolve itself, when you have a Proustian moment and time slows until you remember the feeling of the sun streaming through your childhood bedroom, when you hear all the instruments individually, when you find yourself standing in front of un bel homme in line at the café – when you don’t have time to worry about your underwear showing through your dress.

    I have been searching for a low back bra for years and I finally found it. This bodysuit has it all. Va Bien customer service is beyond excellent! They go out of their way to help to find the right style and fit. I usually wear 32DDD. Initially ordered 34E but it was too big 34D is great. Finally I will be able to wear low back dresses! Thank you Va Bien.

    Cups run full so had to exchange but with the right size gave good bust support for the low back.

    I’m normally a 32DD and the 32C fit well (initially I ordered 32D and it was too big). It worked beautifully for my backless dress – was seamless and did not show through my very tight white dress. It was not at all slimming for me though – it just provided support for my girls. I’m a 24’ waist though so if you are larger it might be slimming for you. As other reviews stated, the length of the torso is longer than average. Would recommend!

    Looks great and works perfectly for what I needed it for.

  5. Jennifer

    This thing was hard to get on and off the first time I put it on. The third and fourth time was much easier after I stretched it out. Requires a bit of gymnastics the first couple times though. I’m 34D, 145 lbs.

  6. RachelS

    Love the corset feel of this piece. But definitely need a long torso to fit properly. I’m 110lbs and 5’5″.Bought a 32D which fit perfectly but definitely wouldnt recommend this for someone bigger. It is very tight and difficult to get in/out of.

  7. Austin Fitzgerald

    I’m a 32DDD I ordered a 34E. The fit was perfect and tight. Definitely need help pulling it off haha but it’s perfect for the few low back dresses I have!

    Fits as expected. I was searching for months for a bra to wear under my low back wedding dress and this is it! I found other bustier bras often came up to high in the cup and showed there and weren’t low enough in the back. This is cut perfectly re: now showing! It’s also pretty supportive. I haven’t worn shapewear much before to say how slimming this is- it’s not too tight.
    The only downside is (depending on body type) there was a sort of reverse muffin top- that is a bulge below where the bodysuit hits the upper thighs/buttocks. A solvable problem with spanx shorts. It’s a little difficult to get on, and I needed assistance getting it off (over head worked best for me) but it solves my bridal undergarment quandy so over all I am thrilled!

Q: How do the cups fit with this style?

A: They tend to fit full, so if you are in between sizes, size down.

Q: Do I have to remove the bodysuit when I use the bathroom?

A: No, the style features a hook & eye crotch closure


Q: Will this bodysuit be long enough for my torso?

A: Our bodysuits tend to have a long stride, however this distance on the garment also depends on how much the piece is filled out when worn.  To help we add 3 rows of hook & eyes on the crotch closure for adjustability.  You can make the piece slightly longer or shorter.
