In celebration of Fashion Week (which officially kicks off tomorrow and boasts a huge Fashion's Night Out celebration throughout the city and beyond Friday), stars attended Fashions Night Out: The Show last night in New York.

Judging from last night's duds, some of my Fashion Week wardrobes to watch include those of Leighton Meester (shown in an edgy, teal cutout bustier dress from Versus), Blake Lively (who pushed her usual style limits in a tribal-print number from Marchesa) and Fashion Week favorite Olivia Palermo (who looked flirty in a floral, off-the-shoulder dress paired with a peony clutch).
