They are specially cut larger so they fit any size head, and differently from ordinary bandanas so they can be tightened to stay on better during sports, even underwater.
You can choose different patterns, such as marine motif, US flag motif, tie-dye, or anything you like. I can also make them with a special logo, like the name of a dive shop (although they're more expensive if I paint a logo on for you.)
The cost is $12 each, including tax and shipping. (Logo bandanas will be more, depending on how many you order.) I can be reached at firstname.lastname@example.org or at (214) 327-0775.
You can also order a custom-made historical costume from Beautifully Made Costumes. I'll do the research and design a gorgeous outfit for you. It could be for a Renaissance Fair, a Victorian event, anything you need. Here are some samples:
A Victorian Lady
The Mad Hatter
St. Nicholas (the Bishop, not Santa Claus)
