Simple Ladies' pirate maiden costume is a great value way to dress up for all kinds of pirate and ocean adventures.
Wear it with long boots or barefooted. It's such a great price it won't matter if you are getting wet in a raft race. It would soon dry out anyway.
This is a dress with a striped top and a jagged hemmed black skirt. You also get a striped headband and a tie on belt and buckle. This costume is not too skimpy but if you'd prefer it shorter you simply need to get the scissors out and cut a bit off the skirt.
