Just to give you confidence, I'm 6' 4", 32" waist and I have had so many compliments about a kilt looking good because I 'have the figure for it.'(No offence intended to any others )
I also thought for a while about the contemporary look, but so far I have found people more understanding about the traditional tartan.I know others opinions should not count, but those first few outings really should be a positive experience. I tend to wear the full kit when I do wear it, but lose the belt and hose for thick socks and boots for a more casual feel. As you will notice from many others on the site, there is no such problem as far as 'pretenders' go if you are a kilt-maker as I'm sure they will understand anyone appreciating their work.
I ended up getting a casual kilt. I really fancied a full dress kilt, but expense (and my wife) forbade it. A 4-5 yard casual kilt is quite full and still has a good swing which is really what stops it from looking like a woman's skirt.I can only second the advice about getting what you pay for. If you try an off the peg rather than a measured kilt you don't expect the fit to be as good.
Happy searching. You'll really enjoy it when you finally decide!
