As you know, I have been a Brooks Brothers customer since I was very young. I regularly peruse the company literature. I recently spotted this quote from Tom Davis, a Brooks Brothers salesman, on the famed Fiat chairman and style icon Gianni Agnelli, who only wore Brooks Brothers button-down shirts:
"Mr. Agnelli loved clothing, and he was like a kid in a candy shop when I took him for a tour around the store...He wore three colors: white, beige, blue. Not stripe, never another color."
I found this quote very timely, as I have similarly limited my shirtings to just a few colours: white, beige, blue, and pink. No stripes, no patterns. Button-down and spread collar. Pinpoint and oxford cloth. That's it.
After completing an audit of my dress shirt collection, I removed all of the unconventional numbers. It may be difficult getting rid of certain items, especially the expensive ones, but it does make things easier in the long run. When you know what you like and what looks good, go with it.
A proper dress shirt is the foundation of the professional chap's wardrobe. Keep it simple, clean, and classic.
Save the flash for interesting ties, watches, and accessories, if you so choose.
