Guests took the dress code seriously at Beth Israel Deaconess Hospital-Needham’s “Great Gatsby Gala’’ on Saturday night. Michelle Lawrence was one of many attendees who channeled Daisy Buchanan for the festivities, which benefited the cancer center and surgical pavilion at BID-Needham. Other revelers included Needham’s Carrie Closuit, Deborah Dorman, and Kristen Capodilupo, and newlyweds Arun and Kelly Ramappa. (Arun is an orthopedic surgeon at BID-Needham.) The night was held at the Putnam Club at Gillette Stadium.
