Good morning and again, thanks for all the feedback. My thoughts...
The cap was not intended to "match" the dress. It is the cap I wear daily and I am skin-bald. The sun wreaks havoc on my scalp.
I have a wonderful all-leather sporran, custom "Goose" inlay from Mr. Haley at Wyvern Leatherworks. However, I use my cantled sporran for "just-a-tick-up" the formality ladder, based on event.
As well, I own a nice pair of Country Shooting hose from House of Cheviot - Brick Red hose with Brick Red & Mustard "chessboard" turnover.
With my Ancient Blue garter ties & my Haggart's Tweed jacket and waistcoat, I wear these for the most formal events I attend.
As for the flashes, I've been having trouble with their length lately. I recently changed how/how far I turn down the cuff, mostly to compensate for a lack of calves. Although I enjoy the tartan flash, I am not satisfied with my elastic flashes either.
Re: the neck tie, I agree. I have been trying locally for a Black & Gold or Red & White Regimental tie...US Army or Cavalry Flag colors. Just havn't located them yet. But, I will.
