Yes! That's the beauty of the customizable inseam length. Our legs are made long, allowing them to fit tall people and pull over the foot for extra coverage and sun protection. The raw hem and internally stitched bar-tacks allow for customizable (unstretched/off the body - will stretch longer when worn) inseam lengths of 31”, 29”, 27”, 25”, 23”, 8", 4", and 2". You can crop the long legs to your favorite shorty length or customize for your height.

See how here.

Our fabric is very stretchy and forgiving, which allows for a comfortable fit for lots of different torso lengths. We've tried them on many people with varying torso lengths and always gotten good feedback! If you're worried about a really long torso, sizing up will give you a little more room too. 

We guarantee you will love your Waterlust purchase or your money back! If you receive one of our products and are not pleased with it for any reason, we would be happy to take it back in its original form for a full refund or exchange within 60 days of purchase.

No restocking fees and free return shipping both ways for orders within the United States. International orders just need to pay return shipping, if exchanging we'll cover the cost to ship the new item back to you.

Known for their show stopping appearance, venomous spines, and voracious appetites, invasive Indo-Pacific lionfish (Pterois volitans & Pterois miles) are the first non-native marine fish to become established in the Atlantic. Lionfish pose a significant threat to local marine ecosystems due to widespread predation of native species, prolific reproduction, and lack of controlling predators.

Advocate Apparel Inspired by the Indo-Pacific lionfish (Pterois volitans & Pterois miles)

Lionfish in their native range, from the South Pacific to the Red Sea, are an important part of the coral reef ecosystem and population numbers are kept in check through natural processes.

However, they are non-native to the Atlantic ocean and have become established as a harmful invasive species in this region, posing a significant threat to local marine ecosystems due to widespread predation on native species, prolific reproduction, and lack of controlling predators. Humans must intervene to reduce their impact in the invaded waters, and our Invasive Lionfish collection exists to promote action and awareness on this issue.

Beginning in the 1980s, two visually identical species of lionfish (Pterois miles and Pterois volitans) were introduced into the Atlantic via the US aquarium trade and have become the first non-native marine fish to become established in the Atlantic. Over the past decade, invasive lionfish densities in these non-native areas have exploded, as they have been documented along the entire US East Coast from Florida through Massachusetts, east to Bermuda, and south throughout the Caribbean. The expansion has been extremely rapid and exponential in scope.

Cute and comfortable!

The pattern looks amazing IRL and it’s more comfortable than I could ever imagine. The cut on the bottom is great and doesn’t ride up at all. I was worried about needing more boob support but the material provides enough support and shaping that you don’t really need anything under it

Impressed

As a 6'1" female, I had given up on trying to wear one piece swimwear. So glad I gave this a try! The fabric is great quality, the sleeve length is perfect and the colors are vibrant. It is extremely comfortable and allows for a great range of motion. The size calculator tool on the site is helpful and accurate. Will definitely be ordering more gear!

Way to go Angela

Not a review but a kudos for your beautiful model Angela who wore this outfit perfectly and showed the average modern woman that it is okay to be comfortable in whatever she chooses to wear. You look great Angela.

Waterlust suit

The patterns are stunning. Unfortunately, I have a problem with the suit, which is in no way a fault of Waterlust, and is not a defect of manufacturing. I have had multiple surgeries on my neck, and the suit fits too snugly around my neck when zipped and worn properly with the zipper in the back. I can wear it with the zipper opening in the front, but then the thumb holes don't line up well, and the bottom edges of the suit aren't shaped to fold correctly when I move my legs.

    We don’t offer free shipping on returns or exchanges for a reason. Transporting items in planes, trains, ships, and trucks is one of the biggest environmental costs of our business, and we think it’s important that our policies reflect that. We offer two options: 1) pay up front and you can send your order back to us within 60 days at no extra cost or 2) wait until you receive your order and pay our $9.95 flat-rate return postage fee if you decide to send something back later on.
