Summary

Sézane Brut Sexy Jean commonly runs small versus US mall denim — French structured cuts sit snug at waist and hip. Size up if between sizes, curvy through hip, or coming from vanity-sized brands. Knitwear is often more forgiving than denim; do not assume one Sézane rule. Partial until more EN URL-backed owner datasets accumulate.
