Free size dresses are upcycled from vintage biboveralls with skirts of other upcycled material (kantha quilt fabric, Indian tapestries, kerchiefs, etc).
Blue tapestry bibs are appropriate for most S-XX due to adjustable elasticized waist (up to 50”), snaps, and adjustable bib straps. Smallest sizes may need to take up hemline, which otherwise sits between ankles and lower shin for most wearers.
