With only a few more days to go for the IIFA awards 2009, we take a look at the top four Best Dressed stars who walked the green carpet last year. No 1 – Ashwarya Rai Bachchan: This time around Ash managed to top the list of the best dressed. With hubby Abhishek in an Armani by her side, Ash looked stunning in a red Dior outfit. She had recieved a lot of flak for the pink lehenga which she wore to IIFA in 2007.
