I'm 100% against wearing a kilt without a sporran in daily wear. You need a short jacket and a sporran for things to look right. A long jacket, combined with the high waist of a kilt, has too much cross-over in my opinion and looks weird (and like a ladies' suit).

I'm also against wearing a kilt that matches the jacket, mostly because I think kilts worn with vests or jackets should be tartan (or, if appropriate, saffron), at least in North America.

These are just my views, though, so you can take them for what you paid for them.
