When Ordering Ladies’ Top Hats or Derbys

Measure in inches around the largest part of the head with the tape measure above brow ridges. If you are going to wear your hair in an upswept hairstyle or if you’re going to be wearing a wig, please take that into account when measuring your head. It is best to measure your head with the wig on.
