This is the last outfit Richard Heene decided to wear before his wardrobe turns to orange.

Heene just turned himself in to the Larimer County Detention Center -- he'll see his Rocky beanie again in about 30 days ... when he'll be eligible for a work release program.

But for now, instead of calling him That Guy Who Put His Kid in Danger Just to So He Can Try and Get a Reality Show ... you can call him Inmate #1279435.
