It’s one cool shirt.

A high school junior convinced nearly 60 students and faculty at Sleepy Hollow High School in Sleepy Hollow, N.Y., to wear the same yellow Hawaiian shirt in their yearbook photos.

“We bought five shirts and about 10 kids knew about it before picture day,” Dave Husselbee told ABC News.

Husselbee said students would pass the shirts to anyone willing to wear it after their photos were taken.

“Some of the staff was unsure but once the chair of the science department decided to do it, all the others were enthusiastic,” he told ABC News.
