In 6 simple steps you can your own cheeky cut bikini bottoms — no elastic needed. Don’t you just hate the way elastic bottoms cut you off in an unflattering way around the hips and cheeks.
DIY Cheeky Bikini Bottoms in 6 Simple Steps
Unlike most cheeky bikini bottoms that are made with elastic, I found one way around this is to sew a double sided bottom and letting the natural stretch of the fabric do all the work. This is going to require a little bit of sewing, but it’s super simple so don’t you worry!
DIY Cheeky Bikini Bottom Materials:
- 1/4 yard of swim fabric (I suggest getting 1/2 yard to be safe, never hurts to have extra)
- Sewing machine or Serger
- All purpose sewing thread (I recommend Gutermann)
- Patience! (this is most important)
- The provided “pattern”, or bikini bottoms to trace
DIY Cheeky Bikini Bottom Pattern
Its pretty simple to use just about any pattern you want. If you have some bottoms with the fit you already love, and just want to make your own version, you can trace them onto paper and use that as your pattern. After tracing them, you can adjust the cut to fit just the way you want. This is where patience comes in. It’ll probably take you a few times until you achieve the exact cut you want, but it’s totally worth it!
If you trace your bottoms, make sure to leave lots of extra room for seam allowance. Er on the side of too much seam allowance, it’s really easy to make them smaller if they turn out too big. If you make them too small… you gotta start over. I usually leave about an inch all the way around.
The pattern above is for XS/S bottoms (0-2). If you want to make them bigger, use some undies or other swim bottoms for comparison to get an idea for how much to add for the correct size. You will have to print or draw on two pieces of computer paper and tape them together to have a big enough worksheet.
DIY Cheeky Bikini Directions
Get your pattern cut out on a piece of paper. Funny thing, I had a front and a back for the pattern, but since my front kept coming out a wee bit small I decided the back works for the front as well! So if you are using the pattern I provided, it is for the front and back pieces. The front is usually just a bit narrower around the thigh holes, not much different. This pattern does not include the seam allowance so you will be adding that extra edge as you cut. If you wish to include the seam allowance in your pattern so that you can cut the exact shape out of your fabric that’s fine too!
Here we have a front and a back pattern but you can use the “back” for both.
You are going to cut out two fronts and two backs, so that the bottoms are double layered. The best way to do this is to fold your piece of fabric in half, so that as you cut you get two identical pieces. It is very important that you cut your fabric out so that the stretch of the fabric goes horizontal. In other words, the fabric should stretch the most from pulling on the sides of the bottoms, not the top to bottom. Most swim knits are 4-way stretch which means you can cut it in either orientation because they stretch vertically just as well as horizontally.
Tack the patterns for both front and back to your fabric with a few pins so that it doesn’t budge while cutting. Next cut out the patterns leaving that extra 1/2 or 1 inch seam allowance all the way around. You should end up with four pieces… two fronts, two backs.
With the “right” or printed sides together, pin the front pieces to the back pieces at the crotch. Sew a seam at the crotch where you pinned. Again if you are using a sewing machine use a zig zag stitch, or use a serger machine on normal settings (DF=N, SL=2.5).
You should now have two identical pieces, each containing a front and back that are sewn together at the crotch.
Lay your two pieces on top of each other so that the printed sides touch and match up perfectly. Tack them together with pins in the center. I do this instead of pinning the edges so that it won’t get all wonky as I remove pins and sew the edges (and you can leave the pins in as you sew). Starting at one of the long edges first (the back top, or front top), begin stitching the pieces together. Since you left a decent amount of seam allowance you can sew a good half inch or so into the edge. This will help prevent the fabric from getting caught in the machine if you are using zig zag. If you are serging align it so that the blade cuts off the correct amount of seam allowance as you stitch.
Sew all the way around the entire outer edges until you get to the last edge which should be one of the sides. LEAVE THAT EDGE OPEN. Do not sew the last edge closed, so that we can right side it out through that hole.
Now the fun part! Inside out the fabric through the hole we left in the side so that we get the printed side out… look at your beautiful work! We are almost done!
At this point, if you think your bottoms are a little too big or wide in any areas, you can inside them back out and stitch over any area you want slimmer. It helps to safety pin them together at the sides and try them on.
These actually ended up a tiny bit too narrow in the crotch, so point in case.. er on the side of too big!
Now we just need to attach the sides together. There are several ways to do this and you can get really creative with it. The tie dye ones I made have little strappy pieces attaching them together at the sides. You can also make little ties or ribbons to sew on and tie them together. Whatever you want! I will go over the simplest method which is just to sew them together. So what about that ugly unfinished edge?
This part can be a little tricky since the fabric is pretty slippery. Take the upper 1/2 inch of fabric from the open edge and fold it inside so you have a little hem. Then take the side you are sewing it to and stick it into the hole 1/2 inch. Sew across this seam. On the other side you will have two finished edges to sew together. I just overlap them by 1/2 inch and stitch right over the top.
If you aren’t worried about the inside edges looking raw, you can simply pinch the two sides together (“right” –or the part that shows– sides together) and stitch across. But if you want them to be reversible use the first method so you have clean hems.
Voila!! You are done! Look at your amazing new sparkly cheeky sexy beach babe bikini bottoms!
