Reviews
"Cut does not fit."
Flattering - Great Pattern
"Loved the fit of this, would buy again."
Runs small
"Just order a size up and safe yourself trying to squash into these suits"
Quality swimsuit
"love the feel of this fabric & the color. This is the 3rd swimsuit I bought from Vit A. The high leg makes a 5’ girl have the appearance of a longer leg. Small was a perfect fit for me at 110lbs"
Very comfortable
"I love the high cut of this swimsuit and the neckline. The material of it makes it feel very luxurious. My only complaint is that it doesn‚'t come with padding. I wish they included it and it could be removed if it wasn‚'t wanted but it makes me hesitant to wear it out in public without padding."
A chic durable and comfortable swimsuit that fit
"The Vitamin A Jenna One Piece is a beautiful and stylish swimsuit with a classic flattering cut. The fabric feels high-quality and durable giving me confidence it will last through many wears without losing its shape. I ordered a size L and the fit is true to size it hugs the body nicely without being too tight or uncomfortable. The straps are secure and the overall design gives a sleek elegant look. It‚'s comfortable enough to wear all day at the beach or pool and I love how versatile and timeless the style is."
Beautiful, just took a bit
"Beautiful, just took a bit of adjusting to the tightness of it. I followed the sizing chart (ordered XS) but should’ve read the other reviews first. A small would have likely felt a bit better on me."
Love it but too small will need to exchange
"Super pretty and great breathable fabric…I’m just a little long waisted so xs was too short for me."
Swimsuit
"Lovely stylish swimsuit with a cut I‚'m definitely not used to! I usually wear full-coverage bottoms and while this style certainly isn‚'t skimpy it revealed more - a little bit more tush and thigh - but not so much that I‚'d feel uncomfortable wearing out in public. I love the square neck cut. I wish the chest had more padding/support though. Felt plenty tight and kept me sealed in."
