@ysmina-- Absolutely! If you check online stores, this hat is actually sold labeled "Sherlock hat" or "Sherlock deerstalker cap." People may not recognize the name "deerstalker" but everyone knows what type of hat we're talking about when we say "Sherlock hat."
I have one too but I only used it when I dressed up as Sherlock Holmes for Halloween. It's a nice hat though, made of wool tweed. I bet it would keep very warm in winter. I don't think this hat will ever go out of fashion completely.
