So as not to make the same mistake, what type of hat (and jacket) do you mean?
In my neighborhood, a cat-in-the-hat style hat, and a plaid jacket with a water squirting flower on the outside pocket. On Shabbos, same thing, but lose the flower. There is a growing subculture that favors big, yellow hats like Curious George’s friend wears. Other communities might be different.
