So now that you have made my Simply Cute Bikini Top you are probably thinking about how cute a crochet bikini bottom would be! Can’t say I blame you because I was thinking the same thing gorgeous. I saw a lot of trendy bikinis with mixed colored trims and elastics but they all had big price tags to go with them. I got to thinking and said, I can make that for just a few bucks and a few hours of my time I bet! That is how this pattern was born! Maybe you haven’t tried my bikini top pattern yet, but still want to make some cute bikini bottoms to mix and match with your other swim tops and that’s awesome too! No matter your reason, these bottoms are simple, easy, and cute! There is a teeny tiny bit of sewing involved (you can hand sew or machine sew) for the elastic but its super easy!

Buying Crochet Supplies Pro Tip: If you purchase any of your craft supplies at Joann Fabrics like I often do, then you should really consider getting the Ibotta App on your phone. They have 10% cashback coupons for Joann’s as well as other cashback opportunities on certain yarn brands like Big Twist. They also have lots of other retailers on there but I pretty much only use the Joann rebates. I have gotten almost $85 back from just buying things I would have bought anyways by scanning my receipt in the Ibotta App. You can have the money sent to your paypal or use it to get gift cards (Joanns, Applebees, etc).

Materials You Will Need

Yarn: I used ICE brand 100% cotton yarn. This yarn comes with 6 small skeins per pack which I love! Any weight DK/sport weight yarn should work for this project though. If you plan on wearing these bottoms in water you will want to use a cotton based yarn. Acrylic yarn does not dry as nicely or as easily as the cotton yarn would. For this project just under one and a half Skeins (125 m per skein) should be enough for most sizes of this bottom.


Crochet Hook: I used a. 375mm Hook. You could use a 3.25mm hook for a tighter stitch as well.

Tapestry Needle: This is a yarn needle to weave in your ends.

Scissors: to cut your yarn. The scissors below are the ones I use and keep in my crafting bag. They are super sharp and compact enough to carry with me and my projects!


Elastic: 5/8″ fold over elastic 8-10 feet of elastic in colors of your own choosing. (around 1/1.5 foot for each leg hole and 3/4 feet to go around the waist twice). Below are some options I found via amazon and think are awesome and perfect if you have amazon prime for free shipping:

Stitches Used in This Pattern

I will be using abbreviations in this written pattern so here is a list of the names/abbreviations and brief directions for each:

Stitch (ST) – Next chain or stitch you are going to work into

Yarn Over (YO) – wrapping yarn around hook

Chain (CH) – After having an slip knot on your hook, YO and pull through your slip knot. That is a chain 1. YO again and pull through loop on hook. That is your chain 2, and so forth.

Slip Stitch (SS) – Insert hook into next chain/stitch and yarn over. Pull through chain/stitch and continue to pull through the loop on your hook.

Chain 1 Space (ch1sp) – The space in the row before where a  “bridge”  was created by one or more chains.

Single Crochet (SC) – Insert hook into next chain/stitch and YO then pull through the chain/stitch. YO and pull through both loops on hook.

Double Crochet (DC) – YO and insert hook into next chain/stitch and YO and pull back through the Chain/Stitch. YO and pull through 2 loops, YO and pull through last two loops on hook.

Sizing: Right Fit For You

I normally buy size medium to large bathing suit bottoms so I would say this would fit most similar body types to increase the size you can add more rows, or add an additional increase in the middle of every row to make the back more full coverage. To make the bottoms smaller just make less rows or start with two less chains in the beginning.

These bottoms are more high rise than your average bikinis and that’s by design  I personally prefer the higher rise bottoms and bonus they are totally trendy right now! If you personally don’t like the high rise look you can do less rows to get a lower cut bikini feel! Make it your own!

Making the Front of the Crochet Bikini

Tie on your yarn to your hook.

Chain 11

Row 1: DC in 3rd Ch from hook and DC across in each CH.

Rows 2-11: CH 2 and turn. (Ch2 counts as first DC in row). DC in each ST across row.

Rows 12-24: CH 3 and turn. We will now increase by two stitches each row, one at the beginning of the row and one at the end. To do this after your CH 3 you will do a DC in the same ST the chain is coming out of. DC in each ST across the row and when you reach the last ST do 2 DC in the same ST.

Row 25: CH 2 and turn. DC in each ST across.

Making the Back of the Crochet Bikini

Tie onto the the first CH you started the front of the top with.

Row 1: CH 2 and DC in each ST across.

Rows 2 – 21: Again we will increase each row by 2. CH 3 and turn. DC in the same ST the chain is coming out of. DC in each ST across the row and when you reach the last ST do 2 DC in the same ST.

Connecting the Sides

CH 26 (or how ever many chains you need to connect to the other side and for it to very LOOSELY, fit around your waist).

Connect to the front part of the top with a SS or SC. SC in each ST across the top.

CH 26 (or however many you did on the other side) SC in each ST across the top.  SS with the first CH of the round.

—- STOP —– At this point please please please try on the bottoms and make sure they fit correctly. You will want the sides to be loose (they will be tightened up with the elastic). Also note that you will have about a half inch around each leg hole and another inch taller on the top from the elastic casing being added.

Creating Frames for Elastic

Now you will begin working in the round.

Top Framing Rows 1-2: Ch 4. Sk a ST and DC in the next. *Ch1, SK a ST and DC in the next* repeat until the end of the row. SS in the 3rd Ch up when you reach the starting chain.

Leg Framing Rows: Attach at the top of either leg hole. CH 2, SK a ST and DC in the next ST. *Ch1, SK a ST and DC in the next* repeat until you reach the other side and attach with a SS. Refer to picture below to see where you tie on to start.

Inserting Elastic Into Crochet Bikini!

Fold the elastic and weave in it in the top two rows of the bikini. Try on the bottoms and pin the elastic together where it feels comfortable. Then weave in the elastic around the leg holes again pinning it where it feels like a snug but comfortable fit. Now sew all the ends of the elastic together by hand or with a zigzag stitch on the machine. I used a “invisible thread” so I didn’t have to change colors but you can use a matching thread to your elastic color.

*helpful tip: I sewed the leg elastic to the bottom waistband elastic on the right side and then fold it over the waist band elastic and sewed the tail end back onto itself on the wrong side of the bottoms (pictured below).

Lastly this part is optional! I added a small strip of elastic in the on the inside of the bottoms. On the back side (the bum side) right in the middle. This creates a scrunch effect on the back. Pin the top of the elastic in the middle of the back. Now begin to sew it down the middle of the bottoms stretching the elastic as you go. The picture below shows the placement of my elastic for reference.

  1. Absolutely love your creation. I’ve been searching the internet the past 2 days for a pattern like this. Do you think it would be okay to do this without the elastic? for either top or bottom

    • I think it would be fine without the elastic, but just keep in mind that the elastic does help keep it more fitted as well as allows for more room for error when sizing. Good luck!
