The more detailed the shirt, the more simple the bottoms should be. Balance is very important. Wear the sleeve length according to the proportion of your arms. Heavy arms look better in cap, 3/4, or long. Skinning arms look best in above the elbow length.
This is a collection of photos compiled for their designers' use of shirts. The shirt is my interest, with an emphasis on design more than color. Shirts in black and white and near shades are my preference.
