Fit Tips for Diving

📏

This style runs big

The string bikini bottom is cut generously — if you're between sizes or on the border, we recommend sizing down. The adjustable high-waisted tie strings mean you can fine-tune the fit after it arrives.

🎀

Fully adjustable strings

The high-waisted bottom features adjustable tie strings that sit above your hips, so your size doesn't need to be exact. Size to your hip measurement and use the ties to customise how high the waist sits.

📐

Size to your hips

Your hip measurement is all you need for the string bikini bottom. Measure at the fullest part of your hips and seat — the high-waisted strings sit above this point and are fully adjustable regardless of size.

🌊

After your first dive

Recycled polyester softens slightly with saltwater and wear. The adjustable ties mean you can re-tie to your preferred fit and coverage level after the fabric settles in.

🔀

Mix & Match Sizes

The string bikini top and bottom are sold separately so you can order different sizes for each. If your chest puts you in a different size to your hips, order each piece in the right size — that's exactly what we designed for.

🪸 Your impact

Better gear should leave a smaller footprint.

The String Bikini is made from 75% recycled polyester for US production and 88% recycled polyester for EU production, giving plastic waste a second life by turning it into a high-performance fabric.

Recycled polyester uses 33% to 53% less energy and produces 54.6% less CO2 emissions when compared to traditional polyester making it a more sustainable choice.

Every order:

Each String Bikini Set plants 3 coral fragments in Bali with Livingseas Foundation
2 corals planted for each String Bikini top and 1 coral planted for each String Bikini bottom
10% is donated to ocean conservation through the Save our Seas Pledge

By choosing The Dive Compass, you're helping give back to the ocean and reduce plastic waste while enjoying high quality performance swimwear made for the ocean

👙 Your Care Guide

Our fabrics are made to handle saltwater, chlorine, and sun.

To keep your gear looking and performing great, we recommend:

Rinse with fresh water after ocean or pool use
Wash cold, gentle cycle, inside out
Hang dry
Avoid dryers, bleach, and fabric softeners

Heat and harsh chemicals can break down performance fabrics over time.

Expert Tip! Wash your gear in a GUPPYFRIEND Washing Bag to protect the ocean by preventing microfiber shedding and extend the life of your gear

Avoid contact with rough surfaces as the fabric can easily pull and get damaged, this includes avoiding velcro from your BCD.

🌱 Fabric composition and certifications

These String Bikinis are made with 75% recycled polyester and 25% elastane for US production & 88% recycled polyester and 12% elastane for EU production.

We ensure premium quality that is ethically sourced throughout the supply chain with the following certifications:

Fabric is OEKO-TEX 100 standard certified
Fabric is Global Recycled Standard (GRS) certified

We use OEKO-TEX™ certified sublimation inks for printing our designs, which means they’re tested and certified to be safe for people and better for the environment.

These inks are specifically made for performance fabrics and permanently bond with the material, so the designs don’t crack, peel, or wash out.

Using OEKO-TEX™ certified inks means:

They’re free from harmful substances
Safer for the people who make and wear our gear
And a more responsible choice for the environment

Seems good quality and a good fit

Hi Don, thank you so much for your nice review and your support of Livingseas! Your donation shirt plants 18 coral fragments and donates one reef star structure to Livingseas Foundation to help reach the 500K corals planted goal! Your support means the world to us!

Great leggings all around! The fabric is soft, the design is beautiful, and the function is excellent. With the rash guard I felt glamorous and sun-safe. Easy to doff during intervals and put back on. The scalloped waistband is a great touch. Will definitely shop with The Dive compass in the future!

Hi Susan, thank you so much for your wonderful review! I'm so happy to hear you love the leggings and felt fabulous in them. You look happy and beautiful on the dive boat! Thanks for sharing the photo 🩵

What a cute and functional way to dive in Bonaire! The top fit beautifully and feels very substantial. The sea foam green matches beautifully with the Octopus print and is very visible while submerged. I felt both sun-safe and thematically glamorous!

Hi Susan, I'm so glad to hear you love the rash guard! It sounds perfect for your Bonaire dives. Thanks for sharing your experience and the beautiful photo 🩵

This is my second set of leggings. So happy they now have pockets!

Hi Amy, we're thrilled to hear you love the leggings with pockets! Thanks for being a repeat customer and sharing your excitement. Happy diving!

So beautifully made. Bright colors. Lovely

Hi Christy! Thank you so much for your lovely words. We're thrilled you love the Ocean Headband. Enjoy your bright and beautiful accessory!
