Loved how it fit and looked in the front but too cheeky in the back for me. More than half my butt was exposed.
I have been a die hard Lucky Bottom girl for some time now! They are tried and true: Secure, supportive, and stay put so I don’t have to worry about any slips in the lineup. Fit is more moderate but very flattering; material is soft and buttery and very very comfortable. I have multiples of the bottom and while I can wear a XS or S - I will say I prefer the fit of the XS to ensure extra security, especially when wearing these bottoms in bigger waves of consequence. If you are between sizes, I would recommend sizing down!
Really liking to surf in this. The coverage is perfect for me, feels comfortable at all times, it’s buttery but also resistant. I’ve gotten compliments on the cool green pattern too!
I've been wearing my September Atoll Top and Lucky bottoms to the pool and the beach and just love the classic fit. It's super elegant and functional, so I can lounge in it or be active and take it out to the surf! The Lagoon Green Stripe print is super fun too and makes me feel like I'm surfing in the 60s which is such a vibe.
I purchased this item few months ago, I enjoyed it very much.
The lucky bottom is a style I have been wearing since the beginning of SEPTEMBER. Erika truly understands what a true surf bikini needs to look and fit like. This bottom is extremely flattering on all body types and absolutely stays on in the surf. I have recommended this bottom to many surfer friends who also all love the style. They are simply elegant and beautiful.
I love everything about the Lucky bottom (and the matching Eden top). I spent a long time searching for a bikini that stays *on* while surfing and this definitely meets that standard. It's also super comfortable and just slips on. The high waist and full coverage bottom are not only feminine and flattering but add a touch of modesty, which I truly appreciate as someone who seeks out more coverage in my surf and swimwear. Definitely my go-to bikini when it comes to surfing. Also, the Plum colour is LIFE! :)
I love the swimwear unfortunately the small was just a little to tight on my waist so I'm going ro try a medium
This was my second September swimwear purchase. I love the colors and always get compliments on the colors and the fit of the suit, which are the two attributes I am a fan of as well. They wash very well and look good over time. I was so excited to see you collaborate with another favorite brand W'Menswear! I had to snatch up a piece from that special collection. Thank you!
Loved the print and the fit! Not too high waisted. Fits true to size. Medium coverage. For reference I ordered a small- I’m 5’2 and 118 lb, and quite curvy. Can’t wait to wear in the water!
i originally bought this because i had burned my bum pretty badly & not only did it prevent this from ever happening again but it stays on perfectly and doesn’t leave a hard tan line. big fan😍😍
heya guys, i recently bought this bikini and IM LOVING IT😍😍 i have a hard time finding a bikini that keeps everything inside the top, in general but especially for surfing and im sooo impressed with how safe the top is despite being super comfortable and light! thanks so much for making these 🫶🏼🫶🏼
This is officially my favorite suit to surf in! The Alaia Surf Suit keeps everything perfectly in place so I can focus on surfing without worrying about adjusting anything. I usually pair it with the Scorpion Rashguard, and together they make the perfect set functional, comfortable, and stylish.
I also love wearing it to the beach with my daughter. We can run around, play, and still feel super cute. The material is amazing you can really tell that Erika and the team at September know exactly what they’re doing when it comes to both performance and design.
This is now my summer staple. Feels very cool with the heat when it’s wet.
I’ve recently been surfing in this top and honestly can’t believe how comfortable a rashguard can be. I’m a redhead, so sun protection is super important and this top nails it. The thumb holes offer extra coverage on the backs of my hands, and the higher neckline gives great protection without feeling restrictive.
What really surprised me is how soft it is. So many rashguards feel rough or end up causing more of a rash, but this one is buttery soft and gentle on the skin, even after long sessions in the water. September really got everything right with this piece functional, protective, and super comfortable.
Suit fits true to size and feels perfect in the Honolulu summer ocean! I hope it lasts forever!
Love the print and the fabric. Perfect for diving !
Great top, fits well and true to size. Super soft material. The print is vibrant and detailed. I surfed in it the other day. It was comfortable the whole time and stayed in place.
Great surf top! Fits true to size and is secure. I am a 34C and the S fits my bust well. I do wish the straps had a bit more elastic for extra support but very pleased with the overall fit, comfort, and functionality!

This top is so good! Super comfy, supportive, and it actually stays in place when I’m surfing or just laying out. The fabric feels really nice and the fit is super flattering. Love the square neckline and the textured fabric. I’ve been reaching for this one nonstop. You can really tell the quality in the fabric!
I love this super cute suit! Double lined so it stays in place while I’m surfing. Awesome color pattern.
Pattern is so cute, fits perfectly, true to size and super Flattering, and for sure the most comfortable bikini i got. Cant wait to have some more September in my closet🌺
I adore this sun crop top/rash guard. The fabric is super soft (I have never tried anything near this soft), and it fits so nicely! Perfect for longer surf sessions in the tropics/during summer, to stay protected from the sun. I used to surf in bikinis only, but this top has been a total game changer now as I want to protect my skin more. The thumbhole detail helps to protect the upper parts of my hands too, and makes it stay in place. Can’t recommend it enough!! Love it!
