There's a couple more outfits I wear for casual events, typically shirts with stripes. Striped shirts and striped sweaters are my favorites, and it's best to wear them all the time, right?

A little rainbow never hurt anyone. 

Or a lot of rainbow. 

Again, a leather jacket would look swell with those shirts, as would jeans and Chuck Taylor sneakers. As well as a pair of round sunglasses.

Blue/green ones work well too.
