If you are looking for something a little different, then why not look in the range of mermaid costumes?

Mermaids are seen as the jewels of the sea and seen to be beautiful and alluring.  What a great outfit to wear to a costume party.  It is the sort of costume that you could get away with at a pirates/fairies party, under the sea party or even at a stretch, a garden party.

Long beautiful hair is needed for this costume, as well as a long glistening tail.  These costumes are cleverly designed so they look like the tail is solid but mermaid costume wearers are able to walk in the costume with ease and able to sit etc.  There are Disney inspired mermaid costumes like the little mermaid, or more general type of mermaid costumes.
