I'd go along with Phil and Moosehead and suggest Black Watch. Its a muted colour scheme, will look good with dark hose, navy blue, lovat green, black or even a dark grey, and you may not want to look too garish when you first step out in a kilt. First two kilts I owned were both Black Watch. Though at the end of the day its not about what we think but you will feel most happy with at the end of the day.
