The shorts speak for themselves so it is better to keep the rest of the outfit subtle. Pairing the shorts with a plain white tailored shirt is the easiest and most effortless option. From there you can either go formal or casual, and here we’ve gone for a more casual look with the cap and sneakers. For a more formal look, you could rock a pair of loafers and add a tie to the shirt. A perfect accessory would be a nice clean looking black bag like this one from Zara.
