There's a very cute, sweet movie that was made in 1986 called Shag, starring Phoebe Cates and Bridget Fonda. It came right on the heels of Dirty Dancing and is about a group of girls who just graduate highschool and spend a weekend at Myrtle Beach. Each girl has her own problem she's dealing with but it's very much about how they are all there for one another. BTW, Shag is not the Austin Power type of "Shag" but it's a type of dance they used to do in the South, kinda like the fox trot or swing dancing type of thing. Anywho it's cute and whenever my sisters and I are staying in for the night, we watch this movie... or Wet Hot American Summer but that movie has NOTHING to do with sisterhood, it's just a hilarious movie!
