Cottesloe Sewalong: How to sew the waistband & underbust band (View D)

Cottesloe waistband and underband View D

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.

Sew along the short ends 1/4″ from the raw edge using a zig-zag stitch or serger/overlock.

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.
