Gents, let's not take off down the "Who can wear what" argument. Some people don't feel it's proper to wear a tartan they don't have a connection to. Others do. The Leatheneck tartan is not official to the USMC though it is embrassed. Wear it or don't wear it. If you wear it be respectful of it. That is all any Marine would expect if you choose to wear it.
