I have to share that I have been sleeping on Equipment. I was originally introduced to the chic brand through Necessary and Proper. The lady of the DC-based duo, Lauren, frequently extolled the label and since I think she has excellent taste, I took her style advice.
I found an Equipment shirt that is perfection on a tall frame. Expensive? Yes, but the shirt is 100% silk and a nice departure from the polyester which brands seem to be using ad nauseum. Keep an eye out of the website because select colors do get marked down and steeply so.
