Steps To Follow For Sewing a Bustier Crop Top

Let’s begin sewing the bustier crop top together AKA the fun part:

Pattern Marking and Inventory

Before you start sewing, cut out all the pattern pieces as listed in the pattern instructions. You should have all the pieces as listed below:

A. Front Top Panel – cut x1 fabric

B. Front Lining Top Panel – cut x1 fabric

C. Front Bottom Panel – cut x2 fabric

D. Sleeve – cut x2 fabric

E. Back Side Panel – cut x2 fabric

F. Back Shirring Panel – cut x1 fabric

Cutting Layout

  • Ensure your garment is cut on-grain for proper alignment.
  • Pin fabric accurately for precise shapes.
  • The provided pattern layouts are nondirectional; additional fabric may be needed for nap or prints.

Sewing Steps

Step 1: Gather Front Bodice

Apply a bast stitch along the neckline and the lower edge of the front bodice top panel, as well as on the lower edge of the front lining top panel.

Pull strings for gathers, adjust to required length, and lock with a stitch.

Step 2: Attach Front Panels

Sew front top panel to bottom panel, right sides together.
Repeat for front bodice lining.

Step 3: Join Front Bodice and Front Bodice Lining

Align right sides together and stitch along the neckline and hemline.

Turn the front bodice fabric right side out, iron neckline, and hemline for a clean finish.

Step 4: Finish Back Panel

Complete the top edge of the back panel by initially folding the seam allowance inward, aligning the fold edge precisely with the seam line. Follow this by folding it over again, with the second fold originating from the seam line, ensuring that the raw edge is concealed within the initial fold.
Press fold for a sharp edge and topstitch close to folded edge.

Get the back panel ready for shirring by marking guidelines at intervals of 0.5 inches.

Step 5: Shirring Back Panel

Wrap the shirring elastic around the bobbin, ensuring appropriate tension without excessive stretching. Employ regular polyester thread for both the spool and needle.
Tip: Take into account the color of the shirring elastic you prefer. Typically, shirring elastic is available in black and white, although you may also find it in various other colors.

Adjust the machine’s tension dial to a long straight stitch, such as 4 or 5 (equivalent to 3 to 4 stitches per inch), and sew the shirring rows on the right side of the fabric.
Tip: Before moving on to your actual garment, practice shirring on a fabric scrap to fine-tune the sewing machine settings.
Ensure the elastic is securely anchored by sewing two stitches, back-tacking two stitches, and refrain from using the needle up/down button or automatic thread cutter.
Even out gathers, steam with an iron to settle the folds, and topstitch on sides of the back panel to secure the shirring.
Tip: Ensure that you do not tighten the elastic while pulling the fabric at the end of each row. Pull the elastic from the bobbin, not from your fabric.

Step 6: Attach Shirred Panel to Back Side Panel

Stitch along the seam line.
Repeat for both sides.

Step 7: Elastic Pockets on Sleeve

Fold the edges towards the wrong side and topstitch along the folded edges. This will form an elastic pocket on both the shoulder and bottom edges of the sleeve, leaving an opening to insert the elastic.

Insert a 10-inch elastic in the shoulder and a 9.5-inch elastic in the bottom portion using a safety pin. The elastic’s width should be 0.25 inches.

Smooth out the gathers and secure the elastic pockets by lock-stitching at the ends to ensure the elastic remains securely in place.

Step 8: Join Front and Back Bodice

Place the right sides together and stitch alongside the side seam seamline.

Step 9: Attach Sleeve to Bodice

Position the sleeve on the bodice with the right sides facing each other. Align the front of the sleeve’s armhole with the front bodice armhole, and then stitch along the armhole seamline.

 Turn the sleeve toward the back, align back armholes with the back bodice armhole, and stitch along the armhole seamline.

Step 10: Stitch Sleeve Side Seams

Align the side seams of the sleeve together and sew along the seamline, making sure to stitch on the wrong side of the fabric. Repeat the same process for the other sleeve.

Step 11: Finish Back Hem

Finish the back hem by folding the bottom edge of the fabric twice towards the wrong side and sewing along the folded hem.

Complete the stitching with a backstitch to secure it in place.
Ensure to tuck the fabric’s edge inside to prevent fraying.
