Even if the sun isn't shining, throwing a Hawaiian themed party, or luau, is a wonderful way to celebrate. Not only can you put up some amazingly cool decorations, but the dress up is fantastic fun! Everyone can get into Hawaiian shirts or dresses which are usually brightly patterned and coloured, with floral prints and pictures of palm trees. Leis and hula skirts are also a vital part of this fancy dress theme, as are other cute items such as hair flower clips. Get all sorts of Hawaiian accessories from shell bras to beach themed jewellery.
