Machine wash in cold or warm water with a mild detergent (no bleach, please!). Hang to dry or tumble dry on low heat. Ironing is optional because wrinkled or pressed, this apron looks good. Approximately 5% shrinkage will occur with the first wash.
Regarding sizing, the bib of this apron measures 10" wide at the very top and gets a bit wider as it slopes down towards the sides. The adjustable straps are very long (about 60"), allowing the apron to be and tied around the front or tied in the back.
