Advocate Apparel Inspired by the largest fish in the sea, the whale shark (Rhincodon typus)

Whale sharks (Rhincodon typus) are fish, not whales - allowing them to hold the esteemed title of "largest fish in the sea" (since sharks are fish too!). These charismatic creatures can reach lengths of 12 meters (40 feet) or more! Despite their large size, they feed on some of the smallest organisms in the sea, plankton. Hanging vertically in the water column they're able to suction feed and filter these tiny organisms through their gill rakers much like a giant vacuum cleaner pulls dust and dirt from a kitchen floor, filtering the fragments into its chamber within.

Unfortunately, approximately 100 million sharks are killed every year by humans, through direct targeted fishing efforts as well as unintended bycatch from other fisheries. The whale shark is one species of shark that is particularly vulnerable to this commercial fishing due to their high value in international trade, in addition to their highly migratory nature and normally low abundance. Research into the lives of these gentle giants can help us to manage their populations and keep these magnificent fish in the ocean where they belong.

5% of sales from your purchase of this product are donated to the Marine Megafauna Foundation

The Marine Megafauna Foundation is helping to shed light on the population structure, migratory patterns, and the conservation requirements of these threatened sharks. Created in 2009, they aim to research, protect and conserve the large populations of marine megafauna (large marine species) found along the Mozambican coastline. Almost all whale sharks encountered by divers are juveniles and most are males. Where the school-bus-sized mature sharks swim, what they eat, and where the females give birth has long been a mystery, however their team is now very close to making these discoveries. 5% of sales from your purchase will go to the Marine Megafauna Foundation for satellite tags that are needed to track the movements of these large female whale sharks.

“Waterlust's support provides critical seed funding for us to rapidly develop and implement whale shark conservation projects in areas where this globally-endangered species is most at risk. This includes Mozambique, where our research and awareness work helped the government decide to fully protect whale sharks just a few weeks ago. We love working with a company that is so committed to making a positive change in the world.”

So small and stiff

I upsized to a large to have more coverage, but the cups barely covered my 36Bs! No stretch in the fabric so I just kept falling out. I was so disappointed! I have loved everything I have purchased from waterlust. The colors were beautiful but this top just didn’t work for me. Sadly I returned it

Plus Size Friendly

Bought this bikini top along with the matching classic bottoms for a beach trip. I've never had a bikini that made me feel confident like this. In the top, I got a 2xl, and in the bottoms, 3xl Can't wait to use it again!!!

Great Quality & Fit

Just received my bikini top and the fabric is think and well constructed. I like the cross back fit and fabric design. Mailed in a recyclable paper envelope.

Finally! Waterlust swimwear

I like this top so much I bought it in the Whale Shark, Eagle Ray, and Parrot Fish patterns. It’s often difficult to find string bikini tops that don’t tie behind your neck and pull! These are comfortable for all day wear. Waterlust fabric is already thicker than most swim wear, but if you prefer to also put in some thin foam cups for extra shaping or modesty, there are openings built into the tops along the sides where you could slide them in.
