SEPTEMBER the Line is doing our part to end single-use plastic. We are so excited to share a project we've been working on since before we launched - new plastic free biodegradable hygiene liners! It's one many steps towards creating more ethical swimwear in our line.
Plastic hygiene liners have played their part in increasing environmental damage from plastic waste, but for us it is yesterday's news. This change may seem small but every action matters when it comes to protecting our Mother Earth from more plastic.
How it works
We are extremely committed to becoming as sustainable as possible - we use high performance recycled Italian fabric, recycled paper and PVC for our swing tags, and now we have developed biodegradable hygiene liners. Each step helps bring us closer to eliminating single-use plastic. When it comes to our design, business decisions, and environmental impact, we believe that less is more. We see sustainability as not only an addition to our practices but our responsibility, identity, and the core of everything we do.

Stumbled across this suit at the Xanadu surf shop on Lombok and loved the green bean print! But ahh the fit is amazing. Truly one of the first surf bikinis that I feel confident wont fly off if I get hit by a big wave. I bought the same style in red too! So cute and *actually functional!
Ahh I'm obsessed. Truly one of the first surf bikinis that I can feel confident wont fly off! I have the matching top and bottom and cannot stop wearing them. I bought the same style in red too! So cute and functional!
The made of this bottom is just perfect…fabric felt soft and smooth while hugging the body perfectly. It’s a modest coverage but still had me feeling free and not restricted in the hips area while surfing! Love love love this:)
The cutting of the top is flattering and felt so secured during my surf session. The print is just perfect. 10/10
If you are extremely fair like me but spend hours in the sun this is your top for no more burns. Covering neck,chest and hands has been a game changer for me in the water. I even wear this top mountain biking! Highly recommend if you want a cute and flattering top but want to take care of your skin.
Amazing surf suit bottom that stays snug if you’re spending hours in the water- I’m always skeptical of lighter prints being see through but this pattern is not at all, it’s a thick material but feels light on the skin. Super happy with these bottoms and have already taken them in three surf trips!
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!
