Instagram contest #concoursmellow: sew, share, win! Until 08/31

Easy to sew, quick to put on, super comfortable to wear, the MELLOW trousers are the perfect sewing project for beginners in trouser making, without compromising on style.

The leg is slightly shortened, soft, and embellished with a side stripe that can be highlighted with topstitching, piping, or by using a contrasting fabric. The front features Italian pockets, while the back has large patch pockets.

The other detail that gives the MELLOW trousers a very neat finish: the elasticated waistband at the back with a trompe l'oeil button placket at the front.

The choice of fabric for sewing your pattern is vast: chic in suiting wool, casual in dupion, remarkable in jacquard, or more structured in gabardine and denim, the hardest part will be choosing!

Available in the Magazine L’Œil Fauve - Issue 13 Summer 2026 (free PDF)
