ships ahoy

so i have a tiny problem. my work christmas party is fast approaching and i don't know what to wear! we are sailing around the bay on possibly the cutest boat ever and its a fancy dress - the theme being the love boat. now i just don't know what to wear - do i dress up like a little fifties sailor girl? tragic 70's disco bling love boat guest? hula girl? if anyone has any suggestions at all they would be greatly apprecitated - i just don't know what to do!
