Brooks Brothers hosted an invitation-only evening of cocktails and shopping Thursday benefiting the Breast Cancer Research Foundation. (October is Breast Cancer Awareness Month.) The guest list included Olympic rower Taylor Ritzel, Katherine Chapman and Tom Stemberg, Stephanie Andrews and Mark White, Elisha and Doug Daniels, Nancy and Rick Kelleher, and Simone and Ted Winston, among many others. . . . Where did all those supermodels who were in town for the MFA’s Mario Testino party lay their pretty little heads? Sigrid Agren, Bianca Balti, Edita Vilkeviciute, Erin Wasson, and hairstylist-to-the-stars Oribe Canales stayed at the Ames Hotel. . . . “Who’s the Boss” actor Tony Danza worked out in the fitness center at the Four Seasons Thursday, and later was seen rollerblading on Boylston Street.
