Best Yarns for Swimwear to Swim in

Next let’s turn to the functional swimwear yarns – the ones you can actually dive into the pool wearing. These all have properties which mean they’re still wearable when they’re wet. They also all tend towards being narrower. This means they’re going to take longer to work up, but the results will be tighter, and the gaps between the stitches will be smaller. This is going to protect you from showing a little too much in your swimsuit, and you’re less likely to need a lining.

Cascade Cotton Fixation

• 98.3% cotton, 1.7% spandex
• Machine washable
• This yarn has the hippy, boho look of cotton, but with a bit of stretch to help it fit better and stay up when wet.
• But, there are some notable gaps in the colors available
• Hook size: F (3.75mm)
• Buy it here

Ice Yarns Swim

• 100% polyamide
• A yarn specifically made for swimwear!
• Doesn’t absorb and hold onto water like natural fibers will
• Fast drying
• But, the color palette is very limited
• Hook size: D (3mm)
• Buy it here

Alize Diva Stretch Bikini

• 92% microfiber, 2% elastane
• Possibly the holy grail of functional yarn to crochet swimwear from
• Holds its shape in water

Alize Diva Plus

Himalaya Bikini

• 100% polyamide
• Lightweight and fast drying
• Easier to get hold of internationally than Alize brand yarns
• But, it’s another narrow one!
• Hook size: B (2mm)

Himalaya Celinda Stretch

• 93% Acrylic, 7% elastane
• Added elastane means the garment stretches with your body and holds its shape when wet.
• The fiber has less of a sheen than the Diva Stretch, if that’s something you want to avoid.
• And it’s slightly thicker, making it a bit easier to work with.
• But, it’s not widely stocked, and some colors can be tricky to get hold of.

What to Look for in Yarn to Crochet Swimwear with?

Before you pick up your hook, it’s important to make sure you’re working with suitable materials. Unfortunately making swimwear won’t work as a stash-busting project if your stash consists entirely of squashy merino wools or hard wearing linens. Some fiber properties to think about when you get started are:

• Softness
• Absorbency
• Sagging
• Drying time
• Color bleeding
• Chemical tolerance

Softness

First and foremost, swimwear sits right next to your skin, and in contact with some pretty intimate areas at that! So, you’ll want a yarn gentle enough to not cause chafing or irritation. Yarns advertised specifically for making swimwear are obviously a solid bet, as are yarns designed for baby garments.

Absorbency

How much water your finished project holds onto is the next big consideration. Regular swimsuits are made with textiles like polyester, polyamide, nylon, or a blend of these. They are all synthetic fibers, and the material is constructed in such a way that it doesn’t soak up lots of water relative to its own weight. Lots of yarns traditionally used for crochet, on the other hand, will hold several times their own weight in water, thus making them heavy and bulky to wear in the pool.

Sagging

When fabrics get heavy with water, they also sag. Which can mean embarrassing gaps at the sides of your swimwear, or gaping holes between your stitches. To get around this, look for yarns with added elastane or spandex to help your garments hold their shape, or use a slightly smaller needle size than the yarn usually calls for, to create extra tension.

Drying time

Wearing a wet swimsuit for hours is cold and uncomfortable. If your creation is actually going to get wet, make it out of yarn that will dry fast, like microfiber or polyamide. Of course, if you’re just going to use your crochet swimwear for sun bathing, tanning, partying or posing, then this isn’t such a concern!

Color bleeding

When you choose a yarn to crochet swimwear from, you also need to consider whether prolonged contact with water (especially chlorinated water) could cause dye from the fibers to bleed across the garment, or rub off on your skin. This is less likely in synthetic materials, and more likely if you choose natural materials made with natural dyes. And of course, it is more likely to be obvious if the colors are dark or bright! if in doubt, make a swatch first and give it a good soaking to test the colorfastness.

Chemical tolerance

The final thing to consider is how well your chosen yarn is going to withstand things like

• Contact with chlorine
• The salt in seawater
• Getting sunscreen rubbed on it
• And being washed in detergent

So yarns aren’t up to being worn as swimwear at all, because they are too delicate. Some are fine, provided you’re prepared to hand wash them. And others can be machine washed over and over again.
