Katie Holmes and her stylist/business partner Jeanne Yang looked to vintage buys for creative inspiration the other day. The duo, who together design the women’s clothing line Holmes & Yang, were spotted shopping at the Chelsea outpost of Artists & Fleas market, which has a home base in Williamsburg, on Tuesday afternoon. Holmes picked up some greeting cards by artist Verrier. Ethan Hawke and the band Rush are among those who have picked up some of Artists & Fleas’ wares.
