Katy Perry, Jessica Alba And Estelle Party For Tommy Hilfiger Flagship Opening

LA's most stylish celebs were out in force on Wednesday night for the new Tommy Hilfiger West Coast store opening. Jessica Alba and Estelle led the way in the fashion stakes, while the usually fash-fabulous Katy Perry fell short when she rolled up in a silky polkadot blouse, frumpy mini skirt and bug-eye shades. What's the deal with celebs wearing sunnies indoors?

The former Mrs Brand should definitely be taking style notes from Jessica Alba, who looked drop-dead gorge and right on-trend in white, white and more white. The 31-year-old was stunning as she wore her long dip-dyed tresses straight and vamped things up with a dark berry lip.

R'n'B singer Estelle (apparently she's more famous in the States than here) was also looking fly. The 33-year-old perfected sports luxe, leather, brights AND did her best for the hair bow resurgence - well played. Not only did the American Boy singer have us googling 'where to but leather jogging bottoms', but she also had us rummaging through our makeup bags for that long-forgotten red lippy.
