Cynthia Rowley's daughter now has her own fashion line.

Maybe it was the stifling temperatures in the city, but New Yorkers decided to make this past weekend a splashy one all along Long Island's South Fork, from the Hamptons all the day to Montauk. In Bridgehampton on Friday night, Sarah Jessica Parker, Kelly Ripa and Jane Krakowski were among the well-known names at Jonathan and Lizzie Tisch's home in Bridgehampton to launch the T&C contributor's new venture, LTD. At the Parrish Museum's annual Midsummer Party in Water Mill on Saturday, art world machers like Robert Wilson and Chat Leat mingled with newcomers like collector Michael Xufu Huang and socialite Larry Milstein. Theirs was a very different crowd from the party at the Surf Lodge to kick-off Kit Keenan's new fashion line of street-wear staples, KIT, which happens to be her name but also a shorthand Montauk visitors would be well advised to remember: Keep it Together.
