This missed the mark ):

I have the bottom and cap-sleeve ones in the same print so got this one so I can mix n match. Unfortunately this gave me the weirdest boob spill and the flattest chest shape. Wish it has pockets to insert my own padding too, the wire at the front warps and flips easily.. I should’ve read the reviews regarding that. Wish I could return this for credit at the very least but I got it on final sale not anticipating it to have so many issues.

Floral haze is the cutest pattern!!

This swimsuit top is so cute, the sleeves are a bit tight at first when you put it on, but it's actually great so it doesn't look loose after wearing it a long time! I would love to remove the wire thing in the middle of the bra because it looks weird on me (maybe because I have a flat chest ?idk)

Floral Haze really is everything, right? We appreciate your honesty about the wire- your feedback helps us make better designs for every body.

Love the unique neckline

I love the way the wire helps hold all the goodies in place and the fit was great. I would size up if you want more coverage. The material feels very durable and comfortable enough to feel like you’re just wearing a shirt! The thing I love about this swim suit top is that it could easily pass with an outfit as well!

Haha! Right, we bet it would pair perfectly with high-waisted shorts or a skirt for a casual look!

Beautiful, Unique Swim Top!

I got the Siren Sweetheart Bikini Top on final sale, and I was not disappointed! Such a unique, beautiful design, perfect for when I'd like a little more coverage. I was also pleasantly surprised that the sleeves are long enough for me given my height! My only critiques would be the sleeves are a little tight on me, and I wish it had a nip cushion layer. I'm 5'11" with a 36C cup size wearing a size Large.

Unique and flattering? Love it! Noted on the sleeves and padding.

Absolutely adore this top!

Such a flattering swim top, and I'm in love with the long sleeves and the back. I have a D/DD sometimes E cup (living in Europe) and ordered a Large (waist: 85 cm, chest: 95 cm), and the top shows quite a bit of cleavage which I don't mind. For the more modest (big chested) girlies I'd say judge for yourself if you're comfortable with this, since I read some reviews on this being an issue for others. But for me, I'm 100% in love and can't wait for summer so I can see how it holds up when swimming. <3

We're delighted that you appreciate the design! Thank you for sharing your thoughts.

FAV!

I love it! It’s so cute! It has good coverage while still making you look cute! Very princessy vibes. It’s thick and seems durable, although there is no patting so you def see some nip, I was worry about that before buying it, you can’t see it in any of the pics but for sure something to think about especially after coming out of the water. I got a size xxs and I wear 32 A, I measured my arms and they are 10 inches not flexing bicep area and 14 inches around shoulder and armpit area… it is a little tight there but it is stretchy so if your arms are thicker maybe size up?…
Hope this helps (:

So glad you love it! Thanks for the heads-up about the fit and padding—super helpful!

Beautiful Top

Absolutely love this top! Can’t wait to wear it on our trip to Cancun to offer a little protection from the sun if I need it. Only gripe is that there’s not a lot of (if any) nipple coverage for me, but I’ll most likely grab waterproof silicone covers to wear underneath. Love the neckline and fit as well! I’m 5’2” , 160lbs, C cup and ordered a size large. Hope this helps!

Thank you for the review Alicia! It looks adorable and we are thrilled that you love it!

super cute!

got this top in white and really love it! it is super flattering on and i love the sleeves since my arms tan faster than my body and im always trying to cover them to even it out.

deducted a star because it came with a stain and the clasp is weirdly hard to do. the hook keeps getting caught on the fabric inside the loops, making it super difficult to push through to the other side.

So cute, some room for improvement

This is such a cute swimsuit. I havent worn it in the water yet so I cant speak to the reviews that say it gets too heavy in the water, but I do know that it’s super cute for lounging around the pool especially on colder days.
Across the whole site, I usually fit a medium top best and that’s still true for the swimsuit too (im 5’6” 120lb). The wire in the middle of the boobs is a little bit awkward. It’s not too visible from afar or in pictures or anything, but I definitely noticed it up close in the mirror. I’m not sure if its just cup size related or what. I think the wire also makes it less forgiving if you’ve ordered the wrong size.
Overall I still like the top a lot.
Last thing I’ll say, I didn’t like the white at first, but when I tried it on with the black surf shorts, I liked it way more.
(The black is a size small, had to return it due to boob squishidge from the wire)

Thank you for taking the time to leave a review! We appreciate your feedback!

Yes, yes, and YES!!!

Oh my gosh to this swimsuit top. I am absolutely in LOVE with the design and how it flatters me up top so well. I have never felt so confident! The quality is beautiful and I wish I could get this in more colors. 100000/10.

Thanks for the positive feedback!

I bought the top in Medium, I didn’t like the fit for my boobs so I decided to buy a new one in large
I’m still waiting on that shipment
Though i worry it will be too wide then and not give any support
I feel like maybe the M would have worked if they didn’t put that wire in the neck line that holds the shape cause it’s not very bendable
If you have smaller boobs you might enjoy this one

Thank you for your review! Our design team will also take your feedback about the wire into consideration for future designs.

Favorite Swimsuit Top!!

This swimsuit top is the perfect item for your wardrobe! I have always been a fan of this company’s “Sweetheart Long Sleeve Crop Top,” and this top resembled that design.

I bought it in a small and an extra small, and I have to guess I did that because XXS was sold out at the time of purchase. My bust is 29 inches and normally I get XXS for the crop top, and when wearing this style of swim tops to the pool/beach, I’ve noticed it gets looser with wear. So, definitely purchase in a smaller size without worrying about the sleeves because they get looser too.

Regardless, I absolutely love this swimsuit. I recently wore it in late May to a girl’s trip in Cozumel, Mexico and it was perfect. Despite temperatures reaching the 90s F and very humid weather, this swimsuit top kept me cool after being submerged in water and kept me warm when the pool got too cool. I don’t care about the weird tan lines it gave me because I was extremely comfortable moving around and swimming in it, plus I know I looked cute while doing those activities.

My only con would have to be the clasp in the back. It’s hard to get on by yourself, and even after getting my friend’s help, she struggled to get it on. At times, I feared it wasn’t secure enough, thus I think that should be the only thing that could be improved about this product.

Overall, I’m happy with the two (Black Rib and Green Rib) I have. Don’t let the long sleeves discourage you from buying it, it’s perfect for hot summer days at the pool or beach because if it was perfect for Mexico, it’ll work everywhere else too.

(Side Note: I know I’ve attached a terrible photo of the top, but it’s the only photo I have of me wearing it.)

We're so delighted that you love it!

Got so many compliments on the unique design

I bought this to go on a recent trip to Kauai. I was stopped by a couple (woman was a photographer) who asked where my swim suit was from and complimented on the design. Lots of friends and family members also complimented me on the unique long sleeve design. This year’s sleeves were designed much better than last year’s. I have the black top from last year and said the sleeves felt too tight, and that seemed to be corrected with this collection. This is my favorite top when I don’t want my arms to tan

You looked great in it! No wonder you received those lovely compliments. We're delighted that our top has become your favorite for sun protection while still looking stylish!

Heart eyes!

Y'all are making me want more of these swimsuits...!! I wasn't sure about the long sleeves, as I fear it'll be too hot in the summer when you are not in the water, but it was so cute I gave in. I have not tried it in the water yet so if it doesn't perform well I'll update my review, but for now I'm in loooooooooove. I was scared the top would not cover enough of my boobs as it looks quite small, but it does! The fit is perfect, true to size. I'm a little scared for the bow, I hope it won't come undone in the water - we'll see. I'll update if it does. I feel like it's suuuuuper flattering. Surpisingly, my boobs are not spilling out and I feel like they are safe enough. The fabric feels nice and thick, and on me, it doesn't seem to be rolling on itself. I feel like the sleeves in the thumbholes area are tighter than other Popflex designs (I have 2 other pieces with long sleeves and thumbholes), so I hope they will be comfortable, but it feels ok still. I do feel like the fabric is maybe a little thick, you might indeed get hot in it, but again, I have not tested it yet. But yeah, I'm kind of in love, I didn't really want two piece swimsuits anymore but the pieces I purchased make me feel comfortable enough to wear a two piece swimsuit. It's soooo cute and I definitely recommend!

Thank you for trusting us and for recommending our product. Happy swimming!

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.
