Some guys will have a closet full of suits, and wear them to work daily or a few times a week/month, or whatever. But then there are guys who don't wear suits generally, but want "a suit" for the few special occasions when they need one (funerals, weddings, interviews, when SWMBO draggs you to the opera, &c.) So, in the interest of helping those guys pick the one right suit to wear, let's start this thread and debate what is the perfect one-suit. I'd go with a medium-wieght, medium gray suit, single breasted and probably a two-button rather than a three-button front. The material should be wool (not cotton like some summer suits), and should be free from any pattern, pinstripes, &c. ... a blank canvas, as it were. This suit gives you considerable "wiggle room", as it were. You can make it sombre for a funeral with white shirt and black tie/belt/shoes. You can be more lighthearted for a wedding with a coloured shirt (pink, lilac, or boring blue) and tie with light brown shoes/belt. It's light enough to wear in the summer without too much discomfort, and with an undershirt it's not uncomfortable in the winter. Okay guys, weigh in with your opinions!!
