So, frustrated, I turned to my aforementioned 10 year old niece and asked her (as she has a great sense of personal fashion) to select a dress for them to wear. Besides, it is her long gams that were bound to be the deciding factor.
I did a simple Google search for 'girls black dress' and came up with three options for her. She picked this little number. Stating - and I quote -
"Well my favoritest dress is the one from JCPenny's: Mesh baby doll dress. It is sooooooooooo cute!!!!"
To me, she is sooooooooooo cute!!!!
