Full pattern details

A broad rounded collar and matching sleeve bands give this relaxed day dress its 1920s character. Flared panels open at each side below the hip, while the continuous front and back keep the silhouette long and simple. The short sleeves are cut together with the body for a soft shoulder line.

This is a digital sewing pattern for making the dress. No finished garment, fabric or printed paper pattern is included.

Choose your size

All 10 pattern sizes, 6 to 24, are included. The body chart covers bust measurements from 78 to 117 cm and hip measurements from 83 to 122 cm. EU reference labels run from 32 to 50; use the measurements below rather than your usual ready-to-wear size.

Body measurements in centimetres
Pattern size / EU reference	Bust	Waist	Hip
6 / 32	78	58	83
8 / 34	80	61	85
10 / 36	83	64	88
12 / 38	87	67	92
14 / 40	92	71	97
16 / 42	97	76	102
18 / 44	102	81	107
20 / 46	107	87	112
22 / 48	112	94	117
24 / 50	117	99	122

Compare both bust and hip with the chart, then review the finished measurements in the download. The dress has a deliberately relaxed shape. Adjust the length and side-panel height to suit the wearer.

Printing and page counts

A4 and US Letter counts include the calibration page, assembly maps and pattern tiles. Each A0 file contains two full-size sheets. The handbook and technical overview are separate files and are not included in the table below.

Fabric, notions and sewing level

Choose a lightweight woven dress fabric with a soft fall and enough stability for the inset corners. Cotton lawn, fine crepe or a suitable viscose can work, with a compatible contrast fabric for the collar and bands. The handbook includes conservative fabric planning estimates for 150 cm fabric. Allow extra for matching directional prints and for a fitting sample.

You will also need matching thread, light interfacing, marking tools and a small hook with a thread eye. The design is unlined. Use a separate slip if your fabric is sheer. Embroidery motifs, machine embroidery files and accessories are not included.

Sewing level: confident intermediate to advanced. The inset corners, collar finish and narrow front slit need accurate marking, careful clipping and pressing.

Pattern pieces and allowances

The pattern has six pieces: front, back, side skirt inset, flat rounded collar, cuff band and front slit facing. The front and back are cut on the fold. Collar and cuff pieces include their inner layers in the cutting instructions.

Allowances are included: 1 cm for construction seams, 2 cm at the dress hem and zero at fold edges. The slit facing has 1 cm at the neckline and no turn-under allowance on its remaining outer edges; those edges are overcast or overlocked as explained in the guide.

Sew a fitting sample before cutting your final fabric.

Color and fabric ideas

Black with ivory gives the rounded collar and sleeve bands a clear outline. Dusty rose with the same ivory trim offers a softer interpretation of the identical dress. These styling concepts preserve the existing continuous front and back, short cut-on sleeves and flared side insets; the original six-piece pattern and technical specifications remain unchanged.

Choose compatible lightweight woven fabrics so the collar lies flat and the 5 cm sleeve bands keep their shape. Sample the contrast against the main fabric after washing and pressing. A plain cloth makes the inset seams easier to read; a directional print needs extra care at the panel joins. These images illustrate color choices, not additional pattern views.
