You have the ultimate advantage in summer when you have to go formal, but yet want to be comfortable and casual. You can choose a pair of khaki or white dress shorts in order to dress up an attire. Button up shirts are a popular trend on guys and they are casual while still looking kind of formal.
This Fashionisto picked out a black button up shirt to go with a white pair of shorts, making a perfect match. It would look a little less dressed up with jean shorts, but the white shorts make a great color coordination. There are various amounts of colors you can choose to color coordinate your outfit in order to make it look a little more formal. Banana Republic is a great place that has a wide guys selection to choose from while providing a sleek look for you.
There are numerous events and activities that go on in the summer that may require you to show your more fashionable side. For example, how about a summer wedding that takes place outside? This Fashionisto's attire would work perfectly, shorts that don't make him too hot but yet a long sleeved shirt that is more formal then a T-shirt. So loose that tie and those uncomfortable, hot dress pants! Dressing yourself up while still being able to be casual is the best attire to afford in summer.
