Friday in Denim

The vest is the whole idea. It does everything a blazer does to a shirt — narrows the torso, gives the shoulder a line, adds a second colour — at a quarter of the weight.

Rigid denim rather than stretch. It holds a straight leg all day, which is what keeps this on the right side of casual.

Why it works

• Navy over white over indigo is one colour family stepped three ways.
• The belt is visible, which is what tells the eye the shirt is tucked on purpose.
• Tan loafers warm up a cool outfit at the floor.

Swap it

The ivory blazer over the top, and Friday becomes Tuesday.
