Best stated “maybe”. Several alumni groups have looked into having custom jackets made to reflect the jacket style of their period in the past. These groups indicate that these jackets would cost over $500.
In general, contact your school directly if they are still operational. The letter should be addressed to the Principal or current School Athletic Director and request the name and address of the current person selling jackets to your school. Other organizations that you might contact are the European Council of International Schools (www.ecis.org), or the Overseas Brat Organization may be able to assist you http://www.overseasbrats.com. If you attended a Department of Defense Education Activity (DoDEA) or Department of Defense Dependents School (DoDDS), you can get mailing addresses, telephone and FAX numbers, email contacts and websites from the DoDEA site (www.dodea.edu).
