Twisted Bandeau Bikini Top




This self-lined bandeau bikini is super simple to make. It's only made of 4 rectangles and doesn't use very much fabric. I was able to make it with 1/4 meter each color. This bandeau could easily cost less than $10, or maybe even free if you have some scrap fabric laying around!

Step 1: Gather Your Supplies

  • bathing suit material or jersey
  • tape measure
  • scissors
  • pins
  • matching thread
  • sewing machine

Step 2: Measure and Cut


1st Measurement:

  • Measure around the fullest part of your bust. (Eg. 34 inches)

2nd Measurement:

  • Take the 1st Measurement and divide that number in half. Add about an inch to that number for seam allowance. (Eg. 34/2 + 1 = 18 inches)

3rd Measurement:

  • Measure how much vertical coverage you want. Add about an inch to that number for seam allowance. (Eg. 6 + 1 = 7 inches)

4th Measurement:

  • Take the 3rd Measurement and add about 2 inches. (Eg. 7 + 2 = 9 inches)


  • 2 rectangles of fabric with the dimensions of 2nd Measurement x 3rd Measurement for the front pieces. I used 2 different colors, so I cut one rectangle of each.
  • 2 rectangles of fabric with the dimensions of 1st Measurement x 4th Measurement for the back pieces.

    I used 2 different colors, so I cut one rectangle of each.

Make sure you cut your fabric so that the stretch is going lengthwise. You may want to cut out paper pattern pieces first to make sure you have the correct measurements.

Step 3: Sew Front Pieces

For sewing with stretchy fabric, a zig-zag stitch should be used. Your sewing machine might have a stitch for stretchy fabric, so you could use that instead.

Fold one of the front pieces in half with the good sides touching and pin. Sew both sides until 1 inch from the fold. Turn right side-out.

Pull the second front piece through the hole created in the first piece. Match the edges on one side of the piece that was pulled through the hole with the good side of the fabric touching and pin. Sew along the edge and get as close as you can to the fold. Do the same with the other side and then turn right side-out.

Step 4: Sew and Attach Back Pieces

Individually fold each of the back pieces with the good sides touching. Pin and sew, creating open-ended tubes.

Baste the open edge of the front pieces. You can do this using a long stitch with the sewing machine or by hand. Pull the threads and evenly space the gathers created.

Stuff the whole front piece into one of the back piece tubes and align one of the gathered edges with the edge of one end of the tube. Match the seams, pin, and sew. Pull the front piece through to the other end of the tube. This should turn everything right side out. Do the same with the second back piece.

To finish the tie ends, fold under a half and inch and sew close to the edge.

Step 5: Done!

    Worked out very well, thanks! Ended up sewing the back together instead of having a tie.

    Cool design wish i could make that but not that good with fabric

    Cool design.

    One possible change, shorten the ties in the back. It looks a bit large for your bodysize, unless perhaps your goal is to stand out a bit with the unique style. Also, if swimming it may be a bit of a drag despite being swim suit material. If playing Volleyball the longer ties may get in the way...

    That's a good point. I liked the look of the over-sized bow, but the ties could always be shortened later.

    If the longer ties are more "you" or "your style", then let them be. I was mostly being a dude and thinking of functiom over form :-p

    I do like thay the ties arw not like a ribbon, bowtie, or shoelace... you're a person after all, not some Christmas/Birthday gift.

    That is fantastic. Well-documented, reproducible, inexpensive, and cute. Not necessarily in that order.
