Mascarón.
The cheapest option. You take different old clothing from your wardrobe and you put it on. The goal: to be unrecognizable. Old blankets, hats, working glasses, old sheets... It uses to be the funniest costume wherever you go.
Harlequin.
A typical Carnival costume. Inspired in old italian street actors, any harlequin suit must have some specific features:
Musketeer.
This costume imitates the old French musketeers uniform in the 17th century. It is composed by a wide brimmed hat with a feather, a vest with a cross on it, a pair of leggins, a pair of leather boots, a pair of leather gloves and a foil ( a very thin sword). Moustache is optional.
Cowboy.
Another typical costume. Inspired in stories from the Far West, a good cowboy costume should include a cowboy hat, a waistcoat, a pistol with belt, a pair of jeans, boots with spurs, a plaid shirt and a handkerchif for your neck.
