Hello and a warm Celtic from Boston, Massachusetts.
Wear whatever you want! The avatar is me in the Irish National tartan. Wear the kilt because it is a real man's garment. Most of the time you will receive favourable comment. The only negative ones are from those jealous of you for all the chicks that it attracts.

I also have a House of Edgar kilt in the County Donegal tartan (spouse's heritage), it is handsome and gets only favourable comment.

Kilt on.
