A unique Signature

I knew I wanted a signature drink at our reception because it would allow us to serve the basics in alcohol and still serve my absolute favorite drink. It's fun, budget-friendly and trendy. But then, I read a wonderful idea to be unique but give guests a few more options ... FOUR themed drinks.

(from left)

SOMETHING OLD
Manhattan

1 1/2 oz whiskey
1 1/2 oz sweet vermouth
1 maraschino cherry

SOMETHING NEW
Japanese Slipper

30 ml Midori® melon liqueur
30 ml Tequila (or vodka, if that's more your style)
30 ml Sweet and sour mix

SOMETHING BORROWED
Bailey's with chocolate syrup and mint

SOMETHING BLUE
I'm still looking for this one. I would like the main ingredient to be vodka. Any suggestions?
