While searching the web, I came across this and found it interesting. Forgive me if this has already been addressed.
I have not heard of Brittanee being seen in a dress, only in the black shorts,top and flip flops.
"She has brown hair with blonde highlights and was last seen wearing a multi-colored shirt, black shorts and flip flops."
"Her father, Chad Drexel said Brittanee was studying cosmetology in high school and frequently changes her hairstyle and hair color."
"She is also interested in fashion and wears trendy, up-to-date clothes."
"Cops say the night Brittanee disappeared she borrowed a teal, purple and black spaghetti strap dress from a friend and was wearing it when she left the motel."
