Welcome!

First, I vote for black hose without a doubt...looks classy!

Next, if you could get some matching flashes made along with your new kilt, that would be top notch! OR, any of the colors in the tartan would work.

As for larger size hose, do a search on the subject here at XMarks; lots of guys have talked about this same situation in the past...and I'm sure some of them will jump into the conversation shortly, but in the meantime, do the search for instant information!
