What you’re paying for in a premium swimsuit

When you see a higher price tag on a swimsuit, it usually comes down to the stuff you can’t see on a hanger. Premium brands put a lot of time, tech, and testing into their garments before they ever land in your wardrobe. Here’s what to look for:

1. Premium fabric

Premium recycled nylon is thicker, holds its shape, and offers much better compression than thin polyester. It is the difference between a suit that hugs you comfortably and one that goes completely baggy after three swims.

2. Double-lining

A single-layer swimsuit might look fine dry, but it can quickly become dangerously sheer once wet. Double-lining requires twice the material, but it means total peace of mind in the water.

3. Proper engineering

Details like flatlock seams and secure straps take time to produce. Quality brands fit-test on real body types to ensure they stay put, while fast fashion scales patterns up mathematically, completely ignoring how curves actually sit.

4. Official certifications

Guarantees like GRS recycled materials, OEKO-TEX safety testing, and UPF ratings cost money to verify. Premium brands pay for rigorous laboratory testing to prove the product does exactly what it says it will do.

The real cost of cheap swimwear

Let's look at the maths behind a bargain, because cheap swimwear often ends up costing you more in the long run.

Fast fashion swimwear typically lasts just one or two seasons before it starts fading, stretching out or losing its elastic bounce entirely. If you buy a $35 swimsuit, wear it for a few beach days, and have to replace it twice a year, you are spending $70 annually. 

There’s also the environmental cost to consider. Synthetic fast fashion swimwear is a massive contributor to landfill. These budget options rarely use recycled or certified safe materials, meaning the planet cops the hidden fee for that cheap price tag.

When is it worth spending more?

Not everyone needs to drop serious cash on a swimsuit, but there are a few scenarios where investing in a premium piece is a total game-changer.

1. For active swim days

It is absolutely worth it if you’re an active person. If you are swimming laps, chasing kids down the sand, or hitting outdoor workouts, cheap fabric will degrade incredibly fast under that kind of real-world pressure.

2. For better fit and support

Investing is smart if security matters to you. If you are tired of the permanent waistband-shuffle, adjusting straps every five minutes, or worrying about mid-wave wardrobe malfunctions, construction quality is the deciding factor.

3. For more CPW (Cost Per Wear)

A well-made one-piece or pair of swim shorts easily doubles as activewear or daywear when paired with a linen shirt, giving you far more outfits out of a single purchase.

When cheaper swimwear makes total sense

To be completely fair, there are times when a premium swimsuit just isn't necessary.

• If you only use your swimsuit super occasionally, say, twice a year on a quick holiday, a $40 suit will probably do the job. It won't get enough sun, salt, or chlorine exposure to break down quickly anyway.
• Cheaper swimwear is also an okay choice for kids. Children grow out of their clothes so fast that they will inevitably outgrow the size long before the quality of the fabric or construction ever matters.
• Lastly, if you are just playing around with a very specific, hyper-trendy style or colour for a one-off dress-up occasion, it makes complete sense not to over-invest in a piece you know you won't be wearing next summer.

The Sheila approach

We built Sheila on a simple premise: your swimwear should handle real life and last way longer than a single summer.

Every piece uses 100% GRS Certified Recycled Nylon that holds its shape across hundreds of wears. For us, features like full double-lining, UPF 50+ sun protection, and extensive fit testing on real shapes are simply non-negotiables.

Because at the end of the day, the best swimsuit isn't the most expensive one on the rack. It’s simply the one that makes you feel damn good every single time you put it on.
