Last night we scampered around Manhattan, desperate for some good people watching and some great fashion. Fortunately, we were graced with both. First, it was cocktails at Prada on Madison Ave., where those involved with charity New Yorkers for Children gathered to take in gorgeous re-issued vintage Prada dresses--we were smitten with a long, lingerie-inspired number--and fall 2010 runway looks re-imagined in rich burgundy, slate and black duchess satin. (The latter will be loaned by Prada to several women attending the gala.) While we could have stayed at Prada all night--sipping cocktails mixed by The Carlyle Hotel's famed bartender--Jason Wu was calling our names.
