The tan shell is by Jenny, a thrift store find in October 2011; the tan straight skirt is by Alfred Dunner, also found in a thrift shop in March 2014; the shoes are Christian Siriano "Shanghai" neutral peep-toe pumps from Payless in April 2011. Other accessories are a white bow, glasses, pearls, and natural hose.
