Sarah Jessica Parker  spent most of her weekend with her twin daughters, Tabitha and Marion, but first she checked out the Friday premiere of Ultrasuede: In Search of Halston during the Tribeca Film Festival . SJP was also dressed to the nines for a ballet event on Thursday , though she was ultra casual for walks with the girls on Saturday in jeans and Sunday in flowy blue. Tabitha and Marion, meanwhile, looked too cute in their Liberty of London dresses . Sarah Jessica has yet to confirm whether she'll get fancy again and join Kirsten Dunst, Jessica Alba, and more  for tonight's Costume Institute Gala  at the Met.
