    Extremely flattering well fitting bathing suit

    Serenity

    Customer photo review of Serenity

    A sexy black bathing suit is a timeless, flattering choice that enhances your shape while keeping a sleek and confident look. It fits comfortably, hugging the body in all the right places without feeling restrictive. The design is high-cut, cutout, with just the right amount of boldness while still feeling classy. Made from smooth, durable material, it holds its shape well and isn’t see-through when wet. Overall, it’s a versatile, confidence-boosting staple that works perfectly for both lounging and styling!! size 36 DD 170 size 29/30

    Love this one piece. The material of this suit is great. I love that it is stretchy. Fit like a glove. The color was beautiful just like the pics online. In love!

    Serenity

    I purchased based off of the size chart and I did end up having to exchange for a size smaller however the medium fits perfectly and it’s super flattering and comfortable!

    Serenity

    It was absolutely beautiful just a little too big so I exchanged it for a medium! Just waiting for my exchange to come in then I can add a photo!

    I'm 5' 6" and my measurements are 32 27 36. An XS fit me perfectly! I did have to be careful pulling it over my hips though. Once I had it on, I noticed it held my boobs in perfectly. Great fit!

    Serenity

    Amazing quality and fits like a glove. I am 5’7 and 138 pounds - the large is perfect

    Customer photo review of Serenity

    The PERFECT white suit. The design is sexy but chic. Well made and definitely hugs in all the right places. I am usually right in between small and medium (5’3, 140lbs, athletic build and very small chest) but followed the sizing rec to size down. Though it’s a little bit more snug on my bottom half, a medium would have def been too big for my chest. So I would say if you are between sizes and have a bigger chest, maybe go up and smaller chest, go down. I cannot wait to wear this for my 40th birthday trip to Italy in a few weeks!

    Love this suit- it’s so unique and really stands out. Also it stays put- no nip slips! I am a size 0 in clothes and got the XS and it fit great.

    Great one piece!

    Customer photo review of Serenity

    Bought XS and S and returned the small due to better hugging at the top when I bend over. Love the color, fit, design, and cheekiness!

    Serenity

    Comfortable, sexy and fashionable!!!!

    Customer photo review of Serenity

    I got so many compliments on this suit!! One of the comfiest one pieces I’ve ever worn.

    Serenity

    Even though I am in the process of returning this because it’s too big in the chest I love the product and the company. The service on the Instagram page dms was the best. Personable and very helpful! I got a medium and I’m 135 pounds, 5,2 and a chest of 34 b/c. The chest was very big and moved if I bent down and I plan on getting a small when it’s back in stock. Highly recommend for a good quality, sexy , swim suit that will LAST!

    Customer photo review of Serenity

    never felt more sexy, the material is better than GOOD AMERICAN swimsuits and better than any swim wear to touch my body! It holds any belly insecurities you might have IN!!! it's a beautiful mauve silky color! Yes a few nip slips but I used double sided tape. No biggie! I like how it shows your breast off, it's just perfect! There's a swimsuit I can not wait to try but is out of stock, so please restock before summers over. I also have to add that I love how there isn't any 2 pieces on this site, I just appreciate that, and I love how it's not so many over produced under quality swim suits as if you were to look at big retail brands. I've told all.my friends about mbm swim. Refrene I'm 5'7 152 lbs and a large c cup, with a little fupa from my beautiful son.

    Serenity

    Absolutely beautiful, fits so well and nicely made! Can’t wait to wear it for my bachelorette party !

    Love love love this suit. Wasn’t sure how much coverage was in the back given most of the photos were front facing, but super cheeky and sexy!! Perfect for a weekend in Miami 😘 amazing quality - can’t wait to order my next one!

    Serenity

    Customer photo review of Serenity

    Great quality swimsuit and very sexy and flattering. I got a medium because the site says to downsize if your in between sizes and I think it may be a tad to small. I was afraid the top part would be too big on the large because of my smaller chest but larger mid section and bottom. Other than that great fit! Nice fabric! Can’t wait to wear it to the beach.

    Serenity

    Customer photo review of Serenity

    Love, love, love this suit! The fabric is great, and I am so excited to wear this on my honeymoon. The slit was a little too big for me, but was something that a single safety pin at the bottom of the slit easily remedied for me. I ordered a size small, and it fit great. I’m 5’5”, about 128 pounds, 33” bust, 26.5” waist, and 36” hips. Hope this helps anyone on the fence! It’s beautiful!!

    Such a gorgeous and sexy suit! Every detail is perfect.

    Serenity

    Seriously amazing! So in love and couldn’t be happier! Comfy but with a good fit! There is some potential for a slip but nothing a little fashion tape can’t fix! Can’t wait to wear it on vacation.
