Still unsure? Flick us an email at support@innerrelm.com - We’re happy to help you find your perfect match.

Our products generally run true to size and are accurately reflected on the sizing guides. If there is an exception, it will be noted on the product description page. Read the product page for any notes on sizing.

Having said this, our swimwear is constructed with premium double lined recycled fabrics to ensure it is supportive while surfing. This material supports and shapes your body without losing shape over time. This means it may feel firmer when on than the flimsy material other brands use. We recommend taking this into account when choosing your size.

If you are in between sizes and prefer a more relaxed fit in swimwear, you may wish to size up.

Please refer to the size guide first and if you still have any sizing questions please reach out and we can help you :)

We’ve made it easy! If you’re in AUS or the USA, start your return here.

We do not charge any restocking fees for exchanges or Store credits on full price orders. However, there is a $8.99/item restocking fee on all refunds and sale returns.

A restocking fee of $8.99 per item applies to refunds and Major sale returns. This helps us cover the costs involved in offering flexible returns — including the free shippign we over on your order over $150, $20 discount we give on first orders, return shipping, payment processing fees.

Every return also takes time and care from our small team to inspect, restock, and process. This small fee allows us to continue providing high-quality service while keeping things fair for everyone.

Our team processes returns twice a week, so once your parcel arrives back at our warehouse, please allow up to 5 business days for it to be checked in and processed. We'll keep you updated via email every step of the way.

If you believe you have received an incorrect or faulty item we apologise and kindly ask that you please email our friendly Customer Support team at support@innerrelm.com with your name, order number, a quick note about the issue, and a photo of the fault or the item you got. We’ll sort it out for you!

If you bought your item through one of our stockists, you’ll need to process your return directly with them. Since it wasn’t purchased through our website, we’re unable to issue refunds, exchanges, or credits on their behalf.

The good news? Most of our stockists have fair and straightforward return policies, so they should be able to help you out.

We don’t usually make changes once an order’s in, mostly because our warehouse team picks and packs orders quickly. But if your order hasn’t been fulfilled yet, flick us an email at support@innerrelm.com and we’ll do our best to catch it in time.

If you have entered incorrect shipping details, please let us know immediately and provide the correct details to support@innerrelm.com

Once an order’s placed, we’re not able to apply discount codes or refund the difference in retrospect.

The good news? Your code will still be valid for your next order (if it’s a one-time use code).

If you’re having trouble applying a code before checking out, send us an email at support@innerrelm.com and we’ll help sort it before you place your order.

We know the feeling—our best pieces don’t stick around for long!

Restocks depend on demand, so if you’ve got your eye on something, sign up for restock alerts on the product page or keep an eye on our socials.

- Rinse thoroughly inside and out with fresh water after each use.

- Hang to dry in a cool, shaded area—avoid direct sunlight, as it can damage the fabric and void warranty coverage.

- Avoid standing on your item while changing.

- Do not use bleach, harsh chemicals, or cleaning agents.

- Not suitable for chlorinated pools or spas.

- Do not iron or tumble dry.

Treat it with care, and it’ll love you back for seasons to come.

You’re not just purchasing a product—you’re investing in quality, comfort, and a community.

Our pieces are purposefully designed and built to last, using premium materials, ethical manufacturing, and thoughtful design.

We don't cut corners in our approach, no fast fashion.

For example, our swimwear uses double lined recycled swimwear fabrics that flatter the body and retain their shape over time. All our pieces avoid cheap ugly white linings, and incorporate engineered panel design and salt resistant hardware for optimal surf performance season in season out.

We are surfers so our products need to work for us. Which is why we take time to test our designs in the ocean under all sorts of different conditions (perks of the job). No wonder our products are trusted by top athletes around the world.
