Wow! I really started something here!

I don't think that anyone will get terribly upset if one showed up wearing albino hose with some of the more formal outfits, especially since they are the easiest to come by.

On the other hand, wearing a montrose, sheriffmuir, or other doublet is another kettle of fish than just wearing an argyll or PC. First off, you are splashing out way more than you would for the less formal outfits (unless you win the thing on eBay or find it at a jumble sale for a steal). They are also much more elaborate outfits.

So, if you are going to that much effort, you should do it properly.
