You can make a costume at home and it will be really unique - just get a blue T-shirt, white pants and white shoes and you already have a Smurf. All you have to buy is Smurf hat and blue make-up.

Other option and probably the easiest one is to buy cute costumes in local shops or online.You can find really cute costumes for Smurfs, Papa Smurf and Smurfette.
Almost all of them include blue shirt, white pants, white hat and you can buy blue gloves and white boot covers too. Smurfette also needs yellow (blonde) hair (wig) and of course white dress or skirt. You can add blue make-up and blue nose too.
It's so easy, isn't it? In no time you and your little ones are ready for Halloween.
