Jack Sparrow costumes are not only for Halloween, they make great play items for make believe and are fun to use at Pirate themed parties, Pirate re-enactment events or just a plain costume party.
Why is pirate re-enactment becoming so popular? Maybe it is a way to escape the confines of a law abiding life without actually doing any harm to anyone. You can pretend to be bad, while still being good. Everyone has a dark side, and this is a tame way to express that side in a functional manner.
Another reason may be a longing to be out on the open seas, untied down to day to day responsibilities and duties. Some see the pirate as a type of Robin Hood; stealing from rich merchants and giving to the poor; themselves.
Unfortunately today there are still real pirates. There is nothing funny or amusing about them, but the pirate that Jack Sparrow represents is from a time gone by when things were simpler and the world was a little easier to understand.
If you buy a Jack Sparrow costume, look for the best quality in accessories and wig. Some costumes just barely represent the figure and look like they will fall apart in one wearing.
