Pattern Mixing Primer
We can't say it often enough: you can mix all the patterns you want, provided the scales are different. This outfit is a perfect example. A superb execution of the "quadruple lutz", translated meaning, patterned suit, shirt, tie and pocket sqaure. The differences in design and scale are what make the outfit look sophisticated rather than contrived.
||For an equally stylish alternative, substitute a solid and make it the tie ? surrounded by patterns, it's just being natty to the nth degree.
