This apron is approximately 33.5 L x 34.5 W from its widest point. Apron features two long straps which make them the one size fit most. The cross-strap design eliminates neck irritation and strain. This apron consists of 3 layers. The top layer is 100% cotton. I used an 80/20 batting in the center and 100% cotton on the back. Machine wash cold and gentle mild soap. Do not bleach. I recommend using a laundry bag in the wash to protect straps from becoming entangled.
