Schoolgirl look, with a little satin elegance.
The blue jumper with the subtle plaid is by Converse One-Star, from Target in October 2009; the red satin blouse is from Wal-Mart's George line in January 2010; the shoes are Mossimo "Velda" red baby-doll oxford pumps from Target in August 2008. Other accessories are shiny bow, scarf, silver jewelry, white belt, and white hose.
A book makes a nice prop, doesn't it?
