How do you make the “perfect Cosmopolitan”? You can try combining vodka, Cointreau, cranberry juice, and freshly squeezed or sweetened lime juice. Or you can pick up a can or bottle of the The Perfect Cosmo by SJP.

If you stop by SJP’s eponymous shoe shop on Bleecker Street today between 4 p.m. and 6 p.m., SJP herself (that’s Sarah Jessica Parker) will be on hand to greet you. (If you can’t make it today, be advised that the happy hour event will be repeated two weeks from today, on Nov. 30). Note that prospective recipients must be 21 or older. Would-be attendees can RSVP at this link to receive a reminder about the event, though walk-ins are also welcome.

The pre-batched cocktail is produced and packaged by Thomas Ashbourne Craft Spirits and sells for $16.99.

SJP (the store) is located at 385 Bleecker Street (bet. Perry and W. 11th Sts.), 212-284-8415.
