The Situation's New Clothing Line -- Cheeseball In Paradise

Mike Sorrentino has officially launched his brand new "Situation Nation" clothing line ... but it looks a lot less fist pump and way more "Cheeseburger in Paradise."

It seems Sitch has abandoned his bedazzled, Ed Hardy-inspired "Jersey Shore" style we've all grown to hate ... and replaced it with stuff that's obviously inspired by Jimmy Buffett's Key West leisure wear line called Margaritaville clothing.

Sitch is selling everything from lip balm ... to laundry bags ... and even $78 track jackets.
