securilty sundress?

Isabelle hasn't latched onto a blanket or favorite toy, but when Briana brought home this sundress that she bought her at a consignment store, she wants to wear it everytime she sees it. If she isn't wearing it she carries it around like a security blanket. She even carried it into Wal-mart the other day. Emilee couldn't believe I let her. But hey if it makes her happy while shopping, then I'm happy!
