More Undies: Bikini Brief Version

Pattern: my own (see below) with help from McCall's DIY style Misses' Tops and Panties M6128 and Misses' Two-Piece Bathing Suits #M5861
Materials: Rayon/Lycra blend + decorative elastic + Wash-Away Wonder Tape

As promised in my last post, I made up the brief version of my string bikini undies. As before, I based them off of a pair I have from Victoria's Secret, and I love them! I can't wait to get more elastic and whip up some more pairs! This one is in lavender with purple decorative elastic and a little white button in the middle.

And here are the accompanying directions:

Cut: FRONT (x1), BACK (x1, along fold), LINING (x1), ELASTIC (two pieces at 18 1/2", one piece at 25")

Step 1: With right sides together, pin along the bottom of the FRONT and BACK. Baste together.
Step 2: Pin the right side of the LINING to the wrong side of the back along the bottom. Stitch. 

Grade seam allowances, clipping the lining allowance the shortest (you may want to remove your basting stitches to do this).

Step 3: Turn the lining towards the front, covering the seam. Baste raw edges together along the sides.
Step 4: With right sides together, sew the panties together at the seams. Fold the seam allowance towards the back, and finish with a flat-felled stitch
Step 5: Place a 1/4" or 1/8" strip of Wash-Away Wonder Tape (or its equivalent) on the wrong side of the fabric along the edge of the leg opening. Use this tape to attach the elastic like so: Distribute the elastic evenly along the leg opening of the undies, stretching to fit. Allow the edge of decorative elastic to peek out from underneath the fabric, if desired.

Stitch, using a zig-zag stitch. On my Janome, I set the zig-zag width to 2.5 and sewed at a 1/4" stitch allowance.

Repeat for the other side.

Step 6: Stitch the ends of the longer piece of elastic together by overlapping the ends and sewing a line of stitches across. Make sure that the elastic isn't twisted. It may be helpful to secure with double-sided, sew-through, wash-away tape before stitching to baste in place.

Step 7: Apply tape as in step 5 to the right side of the upper edge of the front and back of garment. Distribute the elastic evenly along the top of the undies, stretching to fit. It may be easiest to work the back half in two sections, making it easier to pull the elastic taught as you secure it to the tape.

Stitch, as on the leg openings, using a zig-zag stitch. I switched to a thread color that matched my elastic band here because the elastic is on the outside of the garment.

Variations: If desired, add bows, buttons, decorative stitching, embroidery, lace or zippers to personalize the look. The elastic can also be put on the right side of the leg openings instead of the wrong side.
