A t-shirt is great, but not every man fills one like Marlon Brando or Chris Evans. Jeans are perhaps the most democratic garment in all of menswear, worn by everyone from the 1% to real people, but not every man looks great in them, no matter how expensive they are. But in a well-tailored suit, every man looks his best.
The suit is the great equalizer. It puts men of different backgrounds, careers, financial stati, etc. on equal footing. A man can be built like Daniel Craig or like Paul Giamatti. Put each of them in a t-shirt and jeans, and you have two very different things happening. Put them in a reasonably well-made suit that is carefully tailored to each man’s respective shape, and you have two men who look incredible.
One could make a similar argument about just a jacket. Put the right well-tailored jacket with a good pair of jeans, chinos or trousers, and the look can be transformative, making any wearer regardless of body type look really damn good.
Whether it comes from Combatant Gentleman or Bergdorf Goodman, a well-tailored suit elevates every man to his most dignified form.
