#AskGQ: Navy or Gray?
If you’re going to be springing for a single suit it should be between the classic menswear colors of navy or gray. Here’s hoping you’re also thinking solely about solids as a pattern-free suit is going to guarantee you get the most versatile piece for your money. As for the great debate over suit hues, it’s all about figuring out which works best for your needs.
