So dreamy!

I love how this top looks on me! The sleeves are a little long on my baby arms, but that's something I'm used to and can work around! Can't wait for my vaca to show this off!

Thank you for the glowing review!

From a big gorl.

Alright, I'm reviewing this as a 6ft, 300lbs woman with 46DD honktilgalonbonkers.
I ordered a 3x black top.

Pros: it's super cute, I like the little dip v in the front, I think the lining is cute and compliments the black well, I think the arm length and stretch it fantastic. It's solid, no nip nops here to tell everyone the temperature of the water because it's pretty padded there.

Cons: my back boobs are fighting for their lives, the little hook together part fought me multiple times, I have seems unraveling at the thumb holes, and the bottom jeeps tucking under the honksquonkers.

My true feedback of improvement (again I am just a large person with large squonktiglebongers and am not a designer). I think there would be a huge benefit to a send hook or tie in the back between the tie part and the hooking part. Like halfway between the two, for extra security of no flashing innocent bystanders when being a lil fish in the water. I also think it would benefit to make the bottom a little longer. My biggest concern is something untying or unclipping on the back.

I'm not trying to be a person to self volunteer, but I really think yall would benefit from some bigger customers getting a chance to try it and provide some feed back so that maybe clothing options can not only be height adjustable, but maybe figure adjustable. I'd love to help point a few things out on what I've worn or tried.

I love it and it's my fav swimsuit so far in my small swimsuit ownership. (My prior suits are like walmart and fighting for my life in either molded cup bikinis or the triangle ones of pain).

I did size up from a 2x due to having tonbinglebongers larger than the average fruit section, and I'm glad I did. So if you have some larges squonkondonklers, I may suggest sizing up.

Thank you for your honest review and for your suggestions. We will take note of this and let our design team know. Rest assured that the team is working hard on our products and big improvements that will be helpful for our customers.

Rolls down if you’re not a flat Tummy

Super cute. Super soft. Not made for a tummy. Any movement at all and it rolls down and makes you look a mess. Had to return

Thank you for sharing your experience with us! So sorry that it did not work for you.

Cute but holds so much water

This is definitely not a “I’m going swimming” top. I wore it in the pool and it took in so much water. It’s super comfortable dry but since it takes so much water in it becomes heavy. Your towel will be utterly drenched. Pros and cons.

Thank you for the review and feedback!

Sexy and cute bikini top!

I looove this bikini top! Good coverage for my arms but also emphasizes boobs. I wear M and was wondering if I should size up based on the reviews, but I think the size may have been adjusted because M fit me perfectly. The sleeves were a bit long but that's fine. The ribbon in the back is really pretty. It's good quality but the only thing is since the fabric is kind of thick, it doesn't dry as fast and is wet for a long time. Overall very happy with this design and I'll be wearing it all the time!

Thank you for your review! We're glad you love the bikini top! It looks fabulous on you!

Love it, but sleeves are a little tight

I love this top design. I am a B cup, and so I’m not spilling out of the sweetheart neckline when I wear it. I love using this at my pool to tan without getting my arms darker. It also held up when I swam in the pool later. The only thing I would recommend for improvement is to make the long sleeve part a little looser. I was only at the pool for an hour, and when I took it off I was surprised at how there were indentations all down my arm from the seams inside the sleeves

Great review! Thank you for taking the time to write it.
