Welcome to the neighborhood

Kilts...There not just for Scots anymore

Looks like a good fit to me. I would opt for some long kilt socks or if you prefer to wear them pushed down find a black boot sock that will give you a bit more mass around the ankle.

I'd reserve the waist plate style belt for a dressier occasion but for daily wear find a more casual belt similar to what you might wear with jeans only wider (no less than 2" for a Stillwater kilt because of the 24" length is my personal taste.)

Great first kilt though! Congratulations!
