Very comfy and nice!
[This review was collected as part of a promotion.] This S3 sculpting square-neck lace-back one-piece jumpsuit in the shade Indigo is so beautiful and smooth. I love how comfy this is, and the fit is perfect.

Not impressed
[This review was collected as part of a promotion.] Did not like! It doesn’t fit nicely for me and is pretty low cut. Don’t like that you have to tie the back. Fits really weird around the chest too. The pads also came out.

Comfy and Cute
[This review was collected as part of a promotion.] This swimsuit is really cute and comfy. The color is a really pretty blue and I love the square neck and lace up back. The inside is lined with a soft mesh like fabric that makes it supportive without being super heavy or thick. It hugs curves and fits fairly well. I do think the top leans a little on the bigger side but still fits well and is flattering. Now I’m ready for a beach day!

Nice quality bathing suit
[This review was collected as part of a promotion.] This bathing suit feels like it’s quality-made. The material is on the thicker side, and it has a slight compression to it, which helps smooth everything out. The stitching is nicely done, and I really like that the neckline doesn’t show too much cleavage, and the bottom doesn’t show too much skin. Being just over 1 year postpartum with my 3rd kid; my body isn’t totally where I feel most comfortable in a bathing suit, but this one piece helps boost my confidence a little bit.

Quality suit but I wish it had a bit more stretch
[This review was collected as part of a promotion.] I wasn’t sure how this would look with the laces on the back but surprisingly the whole suit was pretty flattering. I do not have a long torso but it felt like the straps didn’t have much stretch and were a bit uncomfortable. Around the chest area there is some fabric that pulls away as a design choice and I’m still undecided on whether I like that.

Flattering and good coverage
[This review was collected as part of a promotion.] It’s usually hard to find a swimsuit that has enough coverage to bend down and move around in without worrying about being exposed while still feeling a little sexy - but this one really nails it. The back details are especially flattering and add a nice touch. I don’t normally go for straight across necklines because they don’t always suit me, but this one felt secure and fit well!
