I must admit I have never seen anyone sporting this look, although i am sure someone does.

It really seems that flashes/garters are worn on the outer side of the leg, although some folks wear them right at the 9 o'clock and 3 o'clock positions and others have them a little towards the front or the back.

Since flashes descend from hand-tied garters, it does seem like knotting them in front might get in the way. But I'm not aware of any specific tradition or story about which way is considered "proper" or any specific meaning to the position of one's flashes.

I look forward to the comments from those more knowledgeable than I.
