For a first try, it's not bad. A little practice donning and draping your plaid will give you the look you want - something that doesn't create a bum-roll around your waist. To handle the problem of the PC's tails being curled up by the plaid, you might consider the solution adopted by the Chief of Clan MacGregor in 1822, as described in a paper by Figheadair (http://www.scottishtartans.co.uk/A_H..._MacGregor.pdf). MacGregor also wore a PC-like jacket with abbreviated tails, but his joined belted plaid had a section in the middle that was un-joined so that the tails could poke through and keep the plaid looking neater. The plaid was also equipped with drawstrings to aid in donning it - which would result in neat pleats/folds every time with a bit of practice. You might also check out J. Charles Thompson's little book, So You're Going to Wear the Kilt, which contains some thoughts on wearing a great kilt/belted plaid as full formal dress. I also recommend Bob Martin's book, All About Your Kilt, to get his ideas about kilts and plaids.
