September is one of my favorite months to sew because the change in weather makes me want to add a mix of pieces to my wardrobe. Some days still feel warm enough for light dresses and skirts, while cooler mornings have me reaching for long sleeves and cozy layers. That’s why I’ve picked these 10 best sewing patterns for September— they’re the kind of projects that feel satisfying to make right now and will actually get worn straight away. From quick tops you can whip up in an afternoon to more detailed pieces like pants or dresses, each one feels like it belongs in a September sewing list.
1. Riley Long Sleeve Henley
Get the patternThe Riley Henley is such a great sew for September because it’s that in-between top you can wear on almost any day. The buttoned neckline gives you the option to leave it open for a relaxed feel or button it up when it’s chilly. The long sleeves add just the right amount of warmth, and the relaxed fit makes it one of those pieces you’ll keep reaching for when you want comfort without looking too casual.
Fabric ideas: Soft knits like cotton jersey or cotton spandex work beautifully for everyday wear. If you want something with more texture, rib knits are a lovely choice and really make the button placket stand out. For a slightly cozier version, try a cotton blend with a little more weight to it.
Styling ideas: The Riley looks effortless with denim and sneakers for daytime, but it also pairs well tucked into a corduroy skirt with boots for a cozy fall outfit. It layers nicely under a denim jacket or cardigan when the evenings get cooler.

The drop shoulder gives it a relaxed, modern shape, and the ribbed trim finishes it off with that classic sweatshirt look we all love. It’s simple to sew, but the results are something you’ll want to wear again and again when the days start to feel crisp.
Fabric ideas: Medium weight jerseys are perfect for a lighter version you can wear on mild days. Fleece makes it extra cozy for cooler evenings, while terry cloth adds a soft, lived-in feel. Ribbing at the cuffs and hem brings everything together for a professional finish.

They’re a project that feels simple but gives you a piece you’ll want to wear on repeat this season.
