Step 1: Cutting your Diamond Bustier Pattern Pieces
Following the Diamond Bustier pattern instructions, calculate your BCD and measure your band size, then trace your pattern pieces for easy fabric cutting. Fold your lace in Half with the Direction-of-Greatest stretch going around the body and align the fold with the Center of your Front Frame.
Align the lace as well with the side edge of the Front Frame Piece.
Narrow the back band by at least 2 inches.

For additional support, you could cut all of these pieces out of Sheer Cup Lining and baste the lace onto the sheer cup and then assemble your pieces.

Construct your Bustier following the pattern instructions until you are ready to apply your Plush Waistband Elastic!


1. Fit the Bustier and trim the Plush Waistband Elastic at either side of your waist
2. Cut two pieces of Skinny strap Elastic to fit DOUBLE the remainder of your waist measurement
e.g. If your Waist is 32 inches, and the Plush Waistband Elastic is 16 inches you would cut two pieces at 16 inches each (they will each be folded in half to create two 8 inch pieces)
3. Fold each piece of elastic in half and sew onto the Plush Waistband elastic, securing the g-hook onto the right-hand side.
4. Bar-tack the strap elastic on the right-hand side to create a loop for the G-Hook to connect to


The finished waistband should look something like this!


1. Cut two 8 inch pieces of Skinny Strap elastic
2. Insert the rings ad fold in half
3. Sew with the raw edge facing the top of the Bustier
4. Flip the strap elastic up and sew flat so it sits comfortably against the body
5. Create an adjustable Strap with a slider and feed through the front ring and sew down onto the back band.
