You may have a perception that short sleeve shirts are for nerds or old men. That isn’t true… if you find the right style. You should never wear a short sleeve solid dress shirt. You can wear a short sleeve shirt with a print, plaid or stripes.
We set up our Dapper Guy Troy McCune with a summer style wearing a red stripe short sleeve shirt. It is also a patriotic color theme. We used a pair of navy chinos instead of denim. The shoes are a crisp white pair or Converse chucks (even though you can’t see them).
