Why This Exists

Some collabs are business. This one is alignment. Matt built From Earth around craft, quality, and a genuine connection to Bali. SEPTEMBER was built on the same. When two people share that kind of vision, making something together isn't a stretch. It's the natural next step.

Quality is great and the fabric

I love how it feels and wear. The only thing is it runs small even if it by the size chart in USA measurements. I always wear a size a Medium but when ordering Medium here it runs a bit small so will need to order the next size up

so obsessed I bought a second color!

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!

My favorite Lucky bottom

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:)

Amazing quality, best surf bottoms

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!

Great quality and bright colors, very cheeky fit

Loved how it fit and looked in the front but too cheeky in the back for me. More than half my butt was exposed.

Secure, Flattering, Stays Put…Perfect!

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!

I love this classic but versatile suit!

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.
