Chris Passavia wears two suits to work. One is from Brooks Brothers. The other resembles a suit of armor.

The 29-year-old Manhattan resident dons the former on weekday mornings before leaving for his job as an attorney at Wollmuth Maher & Deutsch. He wears the other on 14 summer weekends. It's green and white, with a large "L" in the middle. It includes a stick, a helmet and plenty of pads.
