Steampunk Project Poll-ish Thing

I rooted around the dining room last night and found all the pieces I'd cut for the Sam Browne belt and map case. I didn't do further work because I didn't trust myself to do precise cutting (sinus headache), and didn't think of edging straps. But I did get two more pouches finished.

Anyhoo, I decided that I need to make the Sam Brown belt first - the whole thing is going to fall apart (literally), without it. BTW, here's a picture of Gen. Pershing wearing a Sam Browne belt, so you know what I'm talking about: http://en.wikipedia.org/wiki/File:John_Pershing.jpg
It's the kind of belt worn over a military-ish tunic, with a shoulder strap.

Now, the dees for the shoulder strap are going to be permanently attached to the belt (I've figured out how to make them sliding, but I have concerns that method is sub-optimal and will lead to slop - so I'm not doing it for this iteration). Also, given the way the belt portion fastens, one size will not fit all.

Question the first: Robin-size or Ron-size? (Robin is over 200 lbs and in the neighborhood of 6' tall at this point, so he's a not-beanpole adult)

IIRC I have a good half-dozen accessories to hang off of the belt. The whole ensemble could rack up to a pretty chunk of change, and I have absolutely no objection to selling bits on their own.

Question the second: Present as one ensemble, or offer the pieces separately?

Either way, the only way to display this acceptably (in my mind) is on a model. This is, then, the perfect excuse to buy a dressmaker's form. And a military-ish shirt that fits the dummy neatly, so it all looks good. Yeah, I are feelthy merchant scum. Guilty guilty guilty. The various pouches, etc., would be put on the belt. This does make it hard to affix the usual Art Show bid sheets to the actual items. Plus tape, even good low-tack masking tape *WILL* leave marks on leather.

Question the third and last: If I provide clear photographs of each item to be affixed to the actual bid sheets (and a couple clipboards to hang said bid sheets with pictures adjacent to the dummy), is it reasonable to say to an Art Show staff "Please do not use tape anywhere on the leather"?

Hmm. Also need to go find Mary's guidelines on Art Show price-points...
