If there were an official list for show business success, it would be topped with these two must-haves: an elegant evening gown and a good divorce attorney. Fortunately for starlets, singers and anyone else seeking both glamour and conscious uncoupling, there’s Mark Roscoe. From his home base in Valparaiso, Indiana, Roscoe heads both a thriving family law and mediation solo practice and a haute couture atelier, where his clients include Hollywood A-listers, a Carnegie Hall pianist, a Las Vegas headliner and even a young cancer patient who wanted to rock her senior prom. Family law and fabulous clothing are an improbable career combination, but Roscoe pulls them together, seamlessly.

Q. Tell me about your mental process—do you keep law and fashion compartmentalized, or is it more of an integrated flow of ideas?

A. My mind is always flowing back and forth. If I am working on a divorce case, I process it while I am in the studio working with my hands. When you calm your mind, that’s when the magic happens: Ideas come that inspire you. Designing is like architecture—it’s how things work together. In the same manner, a divorce case or a mediation is like putting pieces together: How can I help this family through a difficult time in the best possible way? I am always processing my cases, thinking of ways to approach them and resolve them. I am never just a designer, and I am never just a lawyer.
