Lindsay Lohan -- Scores Clothing Line with Addict Status

Lindsay Lohan is putting her experience with booze and coke to good and profitable use ... she's launching a clothing line called ... MY ADDICTION.

We've learned LiLo has partnered with Civil Clothing to roll out a menswear collection that will be sold exclusively at every 13-year-old skater's favorite clothing store ... PacSun.

We're told Civil Clothing cleverly came up with the name, pitched it to Lindsay and she agreed. The collection starts at $29.95.
