Drag Queen Sizing

Interfacing

Gather the two “4” pieces (Front facing), the “5” piece (Back facing), the two “6” pieces (Front hem facing) and the “7” pieces (Back hem facing) and the corresponding interfacing pieces.

Iron the interfacing onto the wrong side of the pieces to ensure their stability.

Assembling the Body

Take the back pieces and sew the darts closed on the wrong side of the fabric. Sew the two back pieces together, right sides facing, along the center back edge.

Take the front pieces and sew the darts closed on the wrong side of the fabric.

Stack the front pieces, right sides facing the back, and sew along the shoulder seams. You can choose to top stitch along the shoulder seams and center back seam to help flatten out those edges.

Now sew along the side seams.

To give the garment more structure, you can optionally add boning along the side seams and darts. For more help, watch this video: How to sew boning.

Assembling the Facings

For the inner facing pieces, first gather the two front facing pieces and the back facing. Stack them right sides together and sew along the shoulder seams.

Now, gather the two front hem facing pieces and the back hem facing. Stack them right sides together and sew along the side seams.

To finish assembling the facing, stack the two pieces together and sew the seam between the front facing and the front hem facing. Now you have a continuous facing running along the front, collar and hem of the blazer. Serge the outer edge of the facing (that won’t be sewn to the shell of the blazer).

Attaching the Facing

Stack the facing with the front and back assembly right sides facing each other and pin them along the collar, the center front edge and the hem. Sew along this edge. Snip the seam allowance on the curves and trim off any excess seam fabric on the corners.

Turn the garment right side out and press, pressing lapels down. To give the garment more structure, topstitch along this seam. You can also sew horsehair braid around the hem facing to make it stand out even more.

Installing the Sleeves

Take the sleeve piece. Fold the sleeve in half vertically with right sides facing each other. Sew at the inner sleeve seam to close the sleeve. Once stitched, finish the raw edges together on the wrong side using an overlock machine to serge the seam allowance.

Hem the sleeve with a rolled hem by folding the raw edge twice, then topstitching it.

Pin the sleeve cap evenly along the armhole, aligning the notches. Sew the sleeve all around the armhole with a straight stitch...Repeat with the other sleeve.

Finishing the Blazer

Once both sleeves are attached, you can hand tack the facing along the shoulder seams, the center back and the side seams, just to keep it in place. Take small stitches through the seam allowance only so they do not show on the outside.

Install the buttons. You can use them as a proper closure, in this case you will need to place buttonholes on the other side. Another option: using buttons as decorations and closing the front with snaps or Velcro for a quick reveal.
