Blazer and Tailored Jacket Sewing Patterns for Production

The blazer is the garment that most separates one workshop from another: it takes interfacing, a lapel, a collar, fitted sleeves, and lining, and an error in any of those pieces shows in the finished garment. The blazer and suit jacket patterns in the catalog come with the size range for women, men, and kids, and each design went through a sewn sample before being published.

The Modeltex catalog has 32 blazer sewing patterns (19 for women, 7 for girls, 3 for unisex kids, 2 for boys, 1 for men), all approved with a sewn sample and with the size range available on each product page; the most affordable PDF starts at US$23 with the standard size selection.

Blazer styles: fitted, crossover, cropped, and knit

There are fitted blazers with lapels, crossover blazers with a peplum, short blazers with shoulder pads and pockets, cropped blazers with contrast trim, one-button and double-breasted styles, shawl-collar blazers, and open-front blazers with no closure in knit and faux leather. For girls and boys there are blazers with lapels, two-button styles, and a striped lining, plus a men's style with a contrast lapel.

Interfacing, lapel, and lining: where a blazer is won or lost

Interfacing fused with too much heat bubbles; with too little, it peels off in the wash. Always test it on a scrap of the real fabric before fusing the lot. On the lapel and collar, the interfacing defines how the roll line sits: if it is loose, the collar opens and the blazer loses its shape. The lining is cut roomier than the shell and takes a movement pleat at the back, so it doesn't pull on the garment when the arms are raised.

Fabrics and common blazer mistakes in production

Women's blazers are produced in stretch gabardine, crepe, bengaline, wool cloth, and structured knits such as ponte; faux leather styles need a specific needle and presser foot. The more structured the style, the less it tolerates a thin knit. Faux leather can't be pressed with high heat or unpicked, because every stitch leaves its mark. With this many pieces, plotter prints organize the cutting table better than A4 sheets.

Common fabrics for blazers: stretch gabardine, crepe, bengaline, wool cloth, ponte, faux leather.

Frequently asked questions about blazer sewing patterns

What is the difference between a blazer and a suit jacket in patternmaking?

In practice the two names are used almost interchangeably, and the catalog lists both under the same garment. What defines the pattern is the style: fitted or straight, double- or single-breasted, length, lapel type, and whether it has shoulder pads or a lining. Look at each pattern's product page, not just its name.

What interfacing does a blazer need?

Fusible interfacing in the front, the lapel, the collar, and the pocket flaps, and also at the hem of the body and the sleeves. The weight depends on the fabric: a stiff interfacing on stretch gabardine hardens it and makes it bubble. Test the combination on a scrap, at the temperature and time of your iron or press, before fusing the production run.

Can a blazer be produced in knit fabric?

Yes, as long as the knit has body, like ponte, and the pattern is designed for fabric with stretch. The open-front knit blazer in the catalog has less structure than a lapel blazer with buttons. Cutting a woven pattern in knit, or the reverse, changes the fit: the shoulder and the sleeve are the first to fail.

Are there blazers with a kids' size range?

Yes: the catalog includes blazers for girls, boys, and unisex kids with the complete kids' size range, besides the adult ones for women and men. They suit formal and ceremony lines. Each product page lists the available sizes, so you can set up a kids' run without grading anything.
