Crochet Material & Tools


What do we need to make a crochet bikini. A hook and yarn! The type of yarn is essentially important because being a bikini, its structure has to be stretchy and light.

So if we intend to get it wet, my recommendation would be to use a yarn that has elastane and is lightweight like a DK weighted yarn.

These clover hooks are great for beginners and seasoned crocheters alike. I like them because of the soft silicone grip and the bright colors that tell them apart. For cascade yarns, I would usually use hooks between the size of 2mm and 2.5mm. These 2 sizes work really well with DK weighted yarns.

For most of my crochet bikinis, I use this aluminum 2.25mm hook most frequently up to this day. However, because of its narrowness plus many hours of crochet, I added these soft grips to protect my fingers and they work amazing! 

So now that we have the main ingredients, we would also need the “hidden” essentials such as elastic rubber bandsstitch markers, bra pads, and a measuring tape.

A pair of sharp scissors and a tapestry needle is always good to have as well. As a crocheter, these are your ready-to-go essentials you should already have in your kit! (links attached for easy reference).

Type And Style Of Crochet Bikini


Before we dive in, you should already have your eyes set on something. Pinterest and Google is a great place to start looking. Or if you’d prefer, you can also browse some of our own bikini collections here.

Once we have the style, we would have to figure out if that style fits our body’s shape and type. Here are some quick tips on what bikini style would flatter your body type:

Large chest:  ✅Triangle Bikini Top. ❌ Bandeau

Small chest:  ✅Halter crop top. ❌ Triangle Bikini Top

Wide hips:  ✅Triangle bikini bottoms . ❌High Waist Bottoms

Narrow hips:  ✅ALL (except). ❌ Brazilian style bottoms

Getting The Correct Body Measurements

Sometimes comparing our current bra and underwear size to making a bikini is not 100% ideal. The best way to get the most accurate measurement would be to measure the Height x Width of our bust (see diagram below).


This is the chart we use for The Knotty Lace designs. You will never go wrong if you follow these measurements against our patterns. Note that sizes may differ from other designers’ patterns and websites. More details on how to measure correctly here.

Start measuring under your bust all the way up to the top flat part of your chest. Then again across the whole full cup from left to right.

This will give you your “triangle” cup size when making your bikini top.

And for the bottom measurements, you would need the circumference of the widest part of your hip aka around the bum area.

Most people make the mistake of measuring around the hip bone which will eventually give you a much smaller opening.

You can also refer to this free Swatch Gauge Calculator to calculate any custom size.
