Miu Miu loves it some young folk. Just look at its fall campaign, which stars 14-year-old Haley Steinfeld. It made sense then that their Fashion's Night Out in-store event last night was brimming with the under-21 set. The party was hosted by teen fashion bloggers Tavi Gevinsin, Jane and Judy Aldridge, as well teen fashion plates Harry and Peter Brant and Gagosian muse/fashion editor Shala Monroque. Oh, youth!
