For autumn, sew pieces that layer: a sweatshirt in French terry, a long-sleeve T-shirt, a button-front blouse in brushed flannel, a corduroy pencil skirt, an A-line skirt in wool, tapered trousers in cotton twill, a shift dress in ponte and a kimono jacket in boiled wool as the outer layer. Medium-weight fabrics with some body replace the light cottons of summer, and the garments are cut closer to the body so they fit under each other. The one autumn garment outside most home-sewing libraries is the coat; a boiled wool kimono jacket is the closest you can sew without tailoring.
What changes about fabric in autumn?
Three things. Weight goes up, from the 80 g/m² (2.4 oz/yd²) lawns of summer to 200 to 350 g/m² (6 to 10 oz/yd²) twills, corduroys and sweatshirt knits. Surface changes: brushed, napped and ribbed fabrics trap air, which is what keeps you warm. And colors deepen, so prints give way to texture.
| Fabric | Weight | Why it suits autumn | Sew it into |
|---|---|---|---|
| French terry | 240–300 g/m² (7–9 oz/yd²) | Loops inside trap warmth, smooth outside | Sweatshirt |
| Cotton flannel | 150–200 g/m² (4.5–6 oz/yd²) | Brushed, soft, warm for its weight | Blouse, shirt dress |
| Corduroy | 250–350 g/m² (7–10 oz/yd²) | Pile holds warmth, firm shape | Pencil skirt, trousers |
| Wool flannel or suiting | 250–350 g/m² (7–10 oz/yd²) | Warm, presses crisply, drapes | A-line skirt, trousers |
| Ponte knit | 300–400 g/m² (9–12 oz/yd²) | Stable, warm, no wrinkles | Shift dress |
| Boiled wool | 350–450 g/m² (10–13 oz/yd²) | Felted, no fraying, holds a shape | Kimono jacket |
Napped fabrics (corduroy, flannel, brushed cotton) must be cut with every piece pointing the same way, or two panels catch the light differently. Add 10 to 15 % to the fabric quantity for a one-way layout.
Which layers should you sew for autumn?
A sweatshirt in French terry
The sweatshirt pattern with a crew neck, ribbed cuffs and hem band is the autumn basic. French terry has smooth knit on the outside and loops on the inside; a brushed version is warmer still. Buy matching rib knit for the bands, or cut them from the terry if it has at least 30 % stretch. A ballpoint needle and a narrow zigzag or a serger handle the seams; the knit fabrics guide covers settings on a regular machine.
A long-sleeve T-shirt in cotton jersey
A long-sleeve T-shirt in a 180 to 220 g/m² (5.3 to 6.5 oz/yd²) cotton jersey, or in a fine rib knit, is the layer that goes under everything else. Cut it close to the body with 0 to 2 cm (0 to 3/4 in) of ease so it sits flat under the sweatshirt and the blouse. A boat neck or a high scoop layers better than a deep V.
A button-front blouse in brushed flannel
The button-front version of the woven top pattern in cotton flannel is a shirt you can wear open over the T-shirt or buttoned under the kimono jacket. Flannel is soft because it is brushed, and the brushing also makes it shift while you sew, so pin more and use a walking foot if you have one. In a checked flannel, match the check at the center front and across the side seams; the flannel sewing post shows how. A viscose twill makes a dressier version with the same pattern.
A kimono jacket in boiled wool
Autumn asks for a jacket. Tailored jackets with collars and lapels, and coats, are outside Sewly's pattern library and outside most beginners' reach, but a kimono jacket in boiled wool gets most of the way there. Boiled wool is knitted then felted, so it does not fray, holds a straight edge without a hem and is warm for its weight. Make it hip length with patch pockets, bind the edges with a wool bias strip or leave them raw and topstitched, and close it with a tie belt or a single large button. The wool sewing post has the pressing settings; wool takes steam well but burns at a cotton temperature.
Which bottoms suit cooler weather?
A pencil skirt in corduroy
A pencil skirt in a fine 21-wale corduroy is the first skirt of autumn: warm, firm enough to hold its line, and good with tights and boots. Cut the pile running up the body for a deeper color, or down for a smoother hand; both are correct, as long as every piece agrees. Press from the wrong side on a thick towel so the pile is not crushed. Corduroy frays, so serge or zigzag the allowances before you sew the vent. The corduroy post goes through needle sizes and the walking foot.
An A-line skirt in wool
An A-line skirt in a wool flannel or a wool blend suiting swings more than the pencil skirt and is easier to fit, because it fits only at the waist and hip. Line it with an anti-static lining so it does not cling to tights: cut the lining from the same pieces 2 cm (3/4 in) shorter and sew it to the waist seam. A knee-length skirt takes 1.2 m (1 3/8 yd) of 150 cm (60 in) wide wool.
Tapered trousers in cotton twill
The tapered option of the pull-on trousers pattern in a 250 g/m² (7.5 oz/yd²) cotton twill or a stretch twill gives a trouser that looks tailored from the outside while an elastic waist keeps it comfortable under a tucked-in blouse. Twill has a diagonal weave that resists wrinkles and drapes better than a plain canvas. Cut them ankle length to show a boot.
Which dress works for autumn?
A shift dress in ponte
A shift dress with long sleeves in a ponte knit is a dress you can sew in an afternoon and wear with tights from October to March. Ponte is a double knit, stable enough to sew like a woven and stretchy enough to pull over the head without a zip. Skip the zip option and use a neck facing or a band. Choose a ponte with some viscose in it for drape; an all-polyester ponte is warm but can pill.
How do you plan the sewing order?
Start with the knits: the T-shirt, then the sweatshirt, then the ponte dress. They share a ballpoint needle and a stretch stitch, and each one is quicker than the last once the settings are right. Then the twill trousers and the two skirts, which share the same elastic or zip waist methods. Finish with the flannel blouse (the buttonholes) and the boiled wool jacket, when the weather is cold enough to want it.
Sew the layers to be worn together, so check the ease between them. If the blouse is to go under the jacket, the jacket needs at least 10 cm (4 in) more at the bust and 2 cm more in the sleeve than the blouse. The ease guide explains how wearing ease stacks across layers. A toile of the jacket worn over the finished blouse tells you more than the measurements do.
What about the coat?
A coat with a collar, lapels, a two-piece sleeve and a full lining is a tailoring project, and no AI pattern maker drafts one well yet. If you want a coat this autumn, buy a dedicated coat pattern and a weekend course, or sew the boiled wool kimono jacket robe length with a tie belt and wear it as a wrap coat. Over a sweatshirt it is warm to about 5 °C (41 °F), and it takes a day to make.
