WHAT!?!??!
Everyone knows Odell Beckham Jr. is obsessed with fashion ... but did you know his closet is the size of a DEPARTMENT STORE?!
The Cleveland Browns star gave a rare glimpse into his wardrobe area on Friday ... showing rows of expensive sneakers, aisles of shirts, sweatshirts and pants and some pretty cool memorabilia on the walls.
The shoe racks alone are enough to fill an entire Foot Locker -- 9 shelves high surround the permitter of the massive wardrobe room ... cleats, boots, casual sneakers, everything.
He's also got top quality entertainment .
