Twenty-Something Girls vs. Thirty-Something Women

Carrie unexpectedly runs into Mr. Big—and his new 27-year-old girlfriend, Natasha—at a Hamptons party. Miranda tries in vain to have some mature fun in the Hamptons. Charlotte pretends to be in her twenties so she can date a cute 26-year-old. Samantha's 25-year-old ex-assistant is hired to throw a big Hamptons party using her Rolodex for the guest list.
