Please help me figure out this hair style!!?

Okay, this hair style is basically, the front half of your hair is short or cut until your chin, and the rest...the back part, is regularly long. I think its the style mandy moore did in 'because i said so'. I reallyyy love this styyle but i have no idea how to tell the hair dresser how to cut it if i dont know what its called! Thanks so much!!!
