This is what I wore to serve beer in a beertent at a music festival (called Hillside). I smelled of stale beer ALL weekend, but it was worth it. Also, I managed to make a few tips, a few eye exchanges with some fine gentlemen; all while Thunderheist, Spiral Beach, Born Ruffians and Akron/Family played.
By the end of the weekend I was a mess, due to 2 nights of camping, and an excess of swimming. Well worth it though.
