Grab your girls and head over to this fun, fizzy, sweet night out at One Girl Cookies DUMBO (33 Main Street) on Thursday, 20 September from 6pm to 9pm. Co-hosted by Brooklyn floral studio Blossom & Branch, you’ll learn the art of floral arranging and sugar paste flower-making–as well as a chance to create your very own boutonierre and of course, decorate your own cupcake. The champagne will be flowing and nibbles will be served. To purchase tickets, email dawn@onegirlcookies.com or call 212 675 4996. Tickets are $35 in advance, $40 at the door on the 20th
