Ado:

First off, welcome aboard! Secondly, they always told us that the only stupid question was the one you didn't ask. With that said, here's my quick and relatively uninformed take on the ghillie shirt.

The ghillie shirt is a traditional look, but not one I could carry off. Pour1Malt does it, and with style and verve. I prefer a collarless shirt, personally, that buttons down. Note: while a ghillie shirt with a kilt is just fine, a ghillie suit with a kilt should be avoided!
