Our aprons are one-size-fits-all for adults, so you don't need to worry about choosing a size. Each apron has adjustable waist ties, so you simply slip the apron on and tie it around your waist, ensuring a good fit. Aprons measure 720mm wide by 900mm long. For our children's apron ranges, we offer two sizes, 3-6 years and 7-10 years, with waist ties to secure.
