Birthday Decisions....

Well my little one will be turning 1 in November so I'm planning her party and the theme is giving me the most trouble! I can't decide! I have a list a mile long of the themes I like! Here are a few: Rainbow Party (seen this on another moms blog and it was adorable!), Hawaiian Party ( live in Hawaii -decorations will be easy to find! perfect), Hello Kitty (alot of this stuff on the island too), Ballerina ( I took ballet for many many years so I love this), Princess (she's my princess!), Minnie Mouse, and Lady Bug (a little over done but cute!).  Any suggestions or vote for one of these???
