Birthday Party

Should I go fun and girly? OR
Casual and Cute???? 
So I have  great friend that turn 25 next week! She has always gone above and beyond for my own birthday even organizing a trip to New Orleans for my 25th birthday a couple of months ago. So i want to make her birthday really special this year!  I have been browsing the web for images of garden parties because this stylish gal is deserving a very wonderfully fabulous birthday party! 

Help me decide which direction I should go in?
