I have a tie
The first is Holly Golightly played by Audrey Hepburn in my all-time favorite movie, Breakfast at Tiffany's. She's just so much fun and she's quirky and beautiful and I love that.
The second is from tv (well, and a movie), Charlotte York played by Kristin Davis in Sex and the City. She is just so sweet. Everyone always says I remind them of Charlotte which I take as a huge compliment because she's always been my favorite on the show
