International hats is a broad category that encompasses a lot of unique styles. Everything from French berets to Chinese rickshaw hats to Swiss tyrolean hats are represented here. If you've got a cultural costume we can make sure it's complete with an international hat.
If you're looking for something European, there are lots of choices. There are several berets for that French painter look. There are several Spanish hats too—black hats with wide, flat, sometimes decorated brims. There's even a Venetian gondolier's hat, or a padre hat for a Vatican look. For a more historical hat there are mob hats, and even knight, viking, and Spanish Conquistador helmets. Compliment your lederhosen by wearing an Alpine, yodeler, or tyrolean hat.
If you're looking for something with a more Asian flair, a Chinese cap could work. Maybe a traditional pointed conical hat is more your style. These hats are common all across Asia and are perfect for topping a regional costume. If you're dressing up as a ninja you'll need a headpiece too. Although if you're a really good ninja nobody will see you anyway.
There are hats for all kinds of other international costumes, too. Dress like an Egyptian in a red fez, or like an Arabian sultan in a turban. Get a faux fur Russian hat to go with your Cossack costume or a sombrero to go with your Mexican poncho.
