Formal fit · measurement first

Measure your head circumference first, then compare it with the product-specific label for the Gemvie Top Hat, Bowler Hat or Pork Pie Hat you are considering.

Each table belongs to the named product. Treat its values as current product references, not as sizing rules for every hat in the same silhouette, and confirm the selector or description on the product page before buying.
