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

“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.”

Cute & comfortable

This swimsuit is definitely cute and for the most part, comfortable, however the sides just under the armpits are loose and create a gap in the fabric. Not great, but I’m using the suit primary under a full body swim suit, so it’s ok for me. I would say this fitting flaw needs to be addressed for sure… there are others that say the same thing about this exact issue on the suit.

Great material butt

Loved the suit but the butt area was way to lose , and very baggy around leg area. Like an old suit that lost the elastic. Rest fit well. Oh well returned and custom service was great.

Wanted to Love this Suit

Beautiful material but the XL does not work for someone with larger breasts. 2XL with its higher cut on top fit perfectly and there was built in bust support but the leg holes and butt were too large.

love it!!

love the material! super flattering cut and design, has full coverage :)

like others have said, wide back leads to some gapping but i’ve had no problem with straps falling off. i’m pretty square shaped, 5’3 and 34/26/35 and the XS fits perfectly, glad i didn’t go with the S!

love everything about this suit, hope to order more soon <3

Good material- fit might need some adjustment

I love the material however the back portion is really wide and the straps fall off often. Additionally- those with larger breasts could use a little more coverage in the front. I found myself having to adjust the bottoms a lot it says no touching but it does ride up quite often for me.

Almost perfect

I absolutely love the patterns on both inside and outside. The fit is great everywhere except the arm/shoulder straps. I have an hourglass shape/sloped shoulders and the straps just don’t stay put with any movement. I’m keeping the suit for very leisurely beach/pool days, but sadly won’t be able to use it for swimming laps or snorkeling like I originally hoped. I’m unsure if it will work under a wetsuit for diving, or if I’ll feel the straps falling around my arms and risk flashing when I peel the wetsuit back off! I also would prefer slightly more boob coverage. Even in a size XL there doesn’t seem to be much room for ample boobs without having them out on full display. Hoping there may be some adjustments to the strap design and I’d jump on the chance to get a better fitting suit!
