Birthday Theme ?

My little girl is turning the Big One in October and I am so, over the moon, excited to get started on her birthday party.  At this moment, the theme, I think, will be a mermaid theme.  Not specifically Ariel from The Little Mermaid but a tasteful mermaid theme .  My first theme idea was a glitter/glamour theme involving a photo booth, boas and sunglasses.   Let's see where this goes!
