Pattern Review: Simplicity 9789 and 9790

Threads #225, Spring 2024
Tested by Rebecca Armitage, Wakefield, Rhode Island. Sewn by Samina Mirza, Katy, Texas Simplicity 9789, view A top and view D skirt. Fabric: rayon/spandex jersey, SawyerBrook.com.

Sophisticated Knits


Skill Level:

This pattern is for the intermediate sewist. Experience helps with managing the invisible zipper insertion into a seam with gathered fabric.

Size Range and Fitting:

Pattern 9789 is sized Misses’ 4 to 20 for busts 29-1 ⁄ 2 inches to 42 inches, waists 22 inches to 34 inches and hips 31-1 ⁄ 2 inches to 44 inches. Pattern 9790 is Women’s sizes 20W to 38W. It fits busts 42 inches to 60 inches, waists 35 inches to 54-1 ⁄ 2 inches, and hips 44 inches to 62 inches.

The skirt has a 6-1 ⁄ 2-inch hemline slit in the left side seam. Both bottoms have a 4-inch-wide contoured yoke with a top edge that sits at the natural waistline.

• The pattern calls for straight stitching throughout. Instead, consider a tiny zigzag stitch (0.5 mm width by 2.5 mm length).
