Measuring – Measure around your head, above your eyebrows and ears with a piece of string. Measure the length of the string with a ruler and compare it with the size ranges listed in the table on the table above and there’s your size! Some of the Sunday Afternoons hats also feature an adjustable sizing system to help ensure a better fit.
