Prison shouldn't totally suck for T.I. because sales for the rapper's clothing line skyrocketed while he was in prison.

A rep for AKOO clothing tells says, the company's sales soared by 25% in the last year … while the rapper served time for drug possession.

The company rep said they hadn't seen such a surge in popularity since T.I.'s MTV reality show "Road to Redemption" premiered in 2009. The rep says they're preparing for another spike in sales — when T.I. is set free next week after completing his drug sentence.
