How to Draft the Jumpsuit Pattern

The pattern is drafted based on the Basic Dartless Bodice Block and the Basic Pants Block. If you are drafting basic blocks for the first time, work them out on graph paper first, then trace onto pattern paper and proceed with the modeling stage. Keep your master blocks for future designs.

IMPORTANT! This model has no zipper and must be sewn only from stretch fabrics.

The side seam length from the waist is approx. 35 cm (13 3/4″).

Tip! For a better fit and hold, stitch the strap to the front of the jumpsuit.

Drafting the Front Bodice (Fig. 2)

Trace the front and back bodice up to the waistline.

From armhole line GG1, raise point GG2 by 1.5 cm (5/8″) along the center front line (adjust depending on bust size). Draw a smooth curve G1-G2.
Draft a grown-on facing along the upper edge, 4 cm (1 5/8″) wide at G2–K.
Along the waistline, extend TT2 = TT1 + 3 cm (1 1/4″) (may vary depending on size). Draw the side seam G1-T2.

Drafting the Back Bodice

Apply the same adjustments as for the front bodice:

T3T5 = T3T4 + 3 cm (1 1/4″). Draft a grown-on facing along the upper edge, 4 cm (1 5/8″) wide at G3–K1.

Drafting the Front Shorts

Lower the crotch curve by 1-2 cm (3/8″ – 3/4″): CC1 = 1–2 cm.
From C1, set inseam length 6-7 cm (2 3/8″–2 3/4″).
Extend hem width by 1 cm (3/8″): H1-H2 = 1 cm.
At the waist: AA1 = TT2.

Shape the front shorts by connecting A-C1-H-H2-A1.

Drafting the Back Shorts

Draft the back shorts in the same way as the front.
At the waist: BB1 = T3T5.
Shape the back shorts through B-C3-H3-H5-B1.
Draft a waistband: DD1 = D2D3 = TT2 + T3T5, width = 3 cm (1 1/4″).

Drafting the Pocket

This jumpsuit features unconventional patch pockets with a shaped outer panel and a center inverted pleat (Fig. 1). Unlike traditional placement, the pockets are positioned on the front, keeping everything visible and easily accessible.

Finished pocket size: 8.5 × 8.5 cm (3 3/8″ × 3 3/8″).
For a 1.5 cm (5/8″) inverted pleat, add 3 cm (1 1/4″) to the inner pocket width.

Tip! Pocket size, shape, and placement can be adjusted according to design preference.

Cutting layout is shown in Fig. 3. Add 1 cm (3/8″) seam allowances and 3 cm (1 1/4″) hem allowance for shorts.

Construction of the Jersey Jumpsuit

Sew the bodice side seams.
Create inverted pleats on the pocket pieces and attach the outer pocket panels. Press and topstitch the upper edges. Finish raw edges on the side and lower edges, then baste in place and topstitch onto the front shorts according to the markings.
Sew the shorts inseam and crotch seam. Sew the side seams.
Join the outer waistband at the short ends. Press seams open. Insert eyelets at the front.

Prepare the inner waistband and press seams open; leave unstitched. Attach from the wrong side of the garment. Stitch casing channels, then insert elastic and drawstring through the opening.

Turn the grown-on facing inside, stitch along the lower edge, and sew two parallel rows for elastic casing, leaving openings. Insert elastic, adjust length, join ends, and close openings. Finish hem with a double-needle coverstitch.
