Tobus,

No, you are most certainly not way off base. I tend to wear my waistcoats fairly snug, well I should say, they fit me properly and are not too large. If your waistcoat fits well, you can always utilize the rear adjuster to either tighten or loosen your waistcoat as you prefer. A waistcoat that is way too large looks sloppy to my eye. So, I am 'with you' on this topic mate!

Below are some of my own examples of how I think a waistcoat should fit with Highland attire - specifically Highland day attire. Naturally, the waistcoats I am wearing below are all bespoke by Kinloch-Anderson, so they are indeed made to my measurments, which there is no doubt, makes a difference versus their 'off-the-peg' counterparts - there is absolutely nothing wrong with the latter, as I own several 'off-the-peg' waistcoats, and jackets.






Cheers,
