The traditional sizing method differs in each country, with size numbers corresponding to different measurements according to country of production. A size 7 for example, can be either 56cm or 57cm.
Therefore at Milliners' Guild, we request clients provide a measurement for a precise fit. Take the measurement around the widest part of head, just above the ears.
