The 30-year-old heiress Tweeted she'll be launching her clothing line at Istinye Park Mall in Turkey.

Beyond her fashion line, Ms. Hilton's merchandising empire has now expanded with the creation of Paris Hilton brand stores in 31 countries. She recently told Variety that when it comes to her products, she thinks "head-to-toe" ... from concept to production.

What an inspiration!
