Fred Astaire wore one. So did Willy Wonka. And now ... Carmelo Anthony is adding himself to list of people who rock the TOP HAT!!
The New York Knicks superstar was sportin' the throwback lid to the Met Gala in NYC last night ... with his wife Lala by his wide.
The gala is a big event in the fashion world -- it's overseen by Vogue honcho Anna Wintour and all sorts of fancy people are invited ... from Tom Brady and Gisele to the Beckhams ... even Victor Cruz.
Nobody rocked a top hat like Carmelo though ... who may now pass "go" and may also collect $200.
