What should I wear for my yearbook portrait?

Graduating senior women:
A simple blouse or sweater, solid colors work best, and simple jewelry.
If you are taking the full graduation portrait sitting, your hands will show in some of the poses, so wear your class ring if you have one.
 
Graduating senior men:
Shirt and tie, with jacket optional.
If you are taking the full graduation portrait sitting, white shirts look best under the graduation robe neckline. Your hands will show in some of the poses, so wear your class ring if you have one.
 
Other senior students and underclassmen:
Where any attire that is comfortable to you. Generally t-shirts with writing on them are not preferable because they distract from the overall portrait. Caps also are a distraction from the quality of the photograph.
