We got tuxedo/LBD-ready this week for some swankier-than-usual style spotting at the Guggenheim for the annual young collectors artist ball sponsored by Chloe. And amidst the jumbo projections of Ryan Mcginley's art (we spotted him on our way out, milling around in a dapper looking tux) Blonde Redhead performed an art-appropriate set and spent the rest of the night wafting around with the likes of Feist and Julia Roitfeld. Although there was plenty of awesome formal attire in the room, from gorgeous twinkly dresses to sweeping floor length satin numbers, there were a few gents/ladies that inverted the black-tie dress code in just the right way, like A-Ron in a Christmassy plaid blazer and Erin Wasson in woolly duck boots.
