I have finally made a bikini! It’s been something I’ve wanted to do for about 3 years now. Ever since I got my serger, I’ve been making my own clothes. Bikinis are definitely necessary to have here in Florida and I knew when I got my serger that I’d be making some. I just used regular thread for this bikini that was already threaded in my serger and it worked fine but if you can, use elastic thread. I love the look of this DIY twist bikini and it’s actually very easy to make!
- Sewing Machine (I used a serger)
- 4-way stretch fabric (lycra/spandex)
- Measuring Tape
- Pattern Paper
- A pair of bottoms to make a pattern from
Measure around your bust plus 2 inches and then divide that number in half. This will be the width of each of the two pieces you will need to cut out. I went with 17″ because I measure 32 inches around plus 2 equals 34 divided by 2 is 17. Cut two pieces of fabric out at 17″ x 14″ and then fold them in half like below. This can be made smaller later on but not bigger so measure twice.
Sew each piece above closed on the side opposite the fold (17″ side), leaving the ends open.
Sew the two pieces together like a sleeve so that it is not closed in the middle. By this I mean you should be able to put your arm through this piece completely once sewn. Then flip right side out and it should look like the above picture.
This is what it will look like inside out.
Fold the fabric in half on the line you just sewed. Taking the top half, twist it once like above. This is the part where you can make the top smaller. I cut off a few inches from the open ends to make the top fit me without falling off. You’ll want to wrap the top around your bust to see if you need to cut any off so that it fits properly.
Fold the open ends in, like above, then sew along that line so that the sewn edge will not be showing when it is worn. That’s it! Top done, now onto the bottoms.
Using a pair of bikini bottoms you already have, make a pattern. I used a pair of underwear that I really like the fit of and cut out front and back pieces according to the way they were stitched. The crotch of the front piece is a little longer than the back piece.
I cut out two pieces of fabric of each pattern piece because I wanted my bottoms to have a sort of lining.
If you want to do the lining like me then pin the pieces together (like above) and sew around the perimeter of the leg holes and top of the waist, leaving the crotch and sides open. Flip the fabric pieces right side out.
*You can skip this step if you don’t want a lining or if your fabric is thick enough without one.
Now connect the front and back pieces by sewing the crotch and two sides together. Flip your bottoms right side out and they are done!
My favorite part about this DIY twist bikini top is that the twist can be worn in the front or the back. It makes it look completely different! You could also wear this under an oversized shirt or romper as a bandeau too. It’s like a two-in-one. I think it would be cool to make this swimsuit reversible, using two different colors of fabric. That would be the ultimate DIY bikini.
