This young chap is right on trend.
The patterned shirt with neutral pants.
Subtle, non blingy, jewellery and shades.
Not sure about the hat, it has brim a bit too wide for me, but sensible in the sun, none the less.
For me, the problem of chinos is how to overcome the ickiness of the 70′s. He does it well, with that electric shirt that is cool rather than loud. Also, good sunnies, great man jewelry and a barbered face.
