If you are making a View D Cottesloe bikini, we are going to finish up today with the waistband and underbust band! Instead of using the thin 1/4″ elastic insertion method along the waistline and underbust like in view C, we will be inserting wider 1″ elastic inside bands which provides extra support.
You can also add a waistband to the low rise bottoms of View C using the same method I’ll show you here. Just note that the pattern piece for the view C waistband is different from the one for view D, so make sure you cut the right one.
Let’s finish this up! Cut your 1″ elastic for the waistband and underband according to the measurements provided in the CUT section of the instructions.
Fold your waistband and underbust band each in half with right sides together, so the short ends are aligned.
Sew along the short ends 1/4″ from the raw edge using a zig-zag stitch or serger/overlock.
Now overlap the cut edges of your waistband and underbust elastic by 1/2″.
Stitch the overlap together using a zig-zag stitch.
Divide the elastic pieces into quarters using pins.
Divide the waistband and underbust band into quarters, as well.
Fold the waistband/underbust band in half, lining up the raw edges.
Insert the elastic inside the band, lining up the quarter pin marks. The raw edges of the band will extend slightly beyond the elastic as it sits inside, encased by the band.
Enclose the bands with the elastic inside by sewing with a zig-zag stitch or serger/overlock along the raw edge.
Once again, divide your band into quarters, and your waistline or underbust into quarters.
Place the band over the bottoms or bikini top, so that the raw edges line up, the band seam matches the left side seam, and the quarter marks of the band match the quarter marks on the swimsuit.
Sew the band to the bikini by stitching 1/4″ from the raw edges using a zig-zag stitch or overlock/serger.
When sewing the bands to the bikini, the elastic inside will be caught in the stitches a tiny bit. This will prevent the elastic from shifting and twisting and will keep your band smooth and strong.
Flip the waistband away from the garment so the seams are pointing towards the garment.
Optional: topstitch next to the seam on top of the seam allowance (on the garment, not the band) using a zig-zag stitch or twin needle.
The process is the same for both the bikini top and bottom. So once you’ve finished one, repeat the same steps for the other!
