Take it from Irish legend, Bono, St. Patrick's Day parties are better in a suit. Sure, you could show up in that same green t-shirt you puked all over last year, but you're better than that. So, before you wake up, slam a bottle of Jameson, and start river-dancing to the nearest drunken bag piper, dress yourself up a bit. Otherwise, you may never find out where the gold at.
Shinesty has you covered for St. Patrick's day outfits for adult men. Make St. Paddy proud in a shamrock suit or green suit for men, St. Patrick's day dress shirt, green suspenders and bow tie, or just go all out and don a suit and then act like a leprechaun in a tree.
