It's hard to snag a picture of Philadelphia's first lady, Lisa Nutter. At special events she's usually decked out in a dazzling piece by Nicole Miller; her amazing locks piled high on her head. She weaves in and out of crowds like a stylish woman who has no interest in being seen.

But we worked our in-the-know fashion magic this weekend.

At Saturday night's Academy Ball, she looked delightful in a navy blue, one-shouldered column gown by Philadelphia designer, Melissa D'Agostino, We think the dress was a lovely choice - the cut and the color worked well.  D'Agostino is one of six designers-in-residence working hard at launching fashion careers at the Philadelphia Fashion Incubator at Macy's. The city hopes the incubator will be a part of a vibrant fashion hub east of Broad Street that will one day be brimming with showrooms, manufacturing facilities and specialty stores. As the program's first year winds down, we'll be checking in with the Incubator for an update.

In the meantime, let's focus on FLOPH - first lady of Philadelphia - whose office reports she made a special effort to wear a gown designed and manufactured locally this year. FLOPH also wore the D'Agostino's gown to one of President Barack Obama's inaugural balls on January 20.
