Having been from the Boston area, gone to school in the Boston area, then stayed here (ok I guess I'm a townie), St. Patty's Day is a big deal here. On this holiday, everyone sounds like they're Leonardo from the Departed, but after his celebratory drinks from winning an Oscar. 

The only thing with drinking, your body temperature becomes an evil little liar. March isn't always the warmest of months, so this outfit is a perfect mix of looking cute and fun, but also staying warm and practical depending on how long you're stuck outside bar hopping. This is true "Boston Fashion," planning outfits according to your drink status. Excuse me while I plan my outfit for AA now......
