Sunny day clothing recently that included suede shoes from Gaziano & Girling, a chalk striped fresco suit by Thomas Mahon, striped shirt by Hemrajani, and a Charvet bow tie.
Pink is perhaps the most complementary color to combine with gray, as light blue is with navy. White in the square, tie, shirt and suit serves to blend the elements together. And medium and dark grays are the best time to wear black shoes.
On that day I was definitely in the pink.
