To determine the size of apron required, check the length from mid shoulder to the length required, normally to the knee, then check the chest measurement and finally the hip measurement. Be sure to advise whether the apron is for a Man or a Woman and select the style. Refer to the relevant style table to determine the size required. For sizes larger than are indicated on the tables, contact us with the measurements to obtain a quote. For two piece apron systems like the Vest & Kilt, please supply both the finished length from mid shoulder to bottom edge of vest and length from the waist to the bottom of the apron, generally the knee as well as the chest and hip measurements.
