Guests attending one South Jersey high school graduation may be turned away if they don't abide by a certain dress code.

Family and friends of Washington Township High School students graduating June 23 could be turned away from the ceremony if they're not appropriately dressed according to school standards, reports NJ.com.

Ceremony tickets being sent home with students will include a friendly reminder printed on them stating a dress code that recommends shirts have collars. Also, no T-shirts, tank tops, jeans or Bermuda shorts. Guests over the age of 12 must wear long pants.

The school board discussed the dress code, which dates back to 1998 but has not been strictly enforced, during its most recent meeting.

Board President Ginny Murphy said, "The board chose to emphasize the policy at the past few meetings because each year we have attendees that show up unaware of the dress code policy. The WTHS graduation is a formal event and as such, appropriate attire is expected."

Improperly dressed guests will not be allowed to attend.
