The design is probably not much changed since the late Victorian era; I love the swoop it has. It certainly also served me well travelling to and from graduation ceremonies in one of my kilts in January.
At one point in my life I was rather keen on joining a Guards regiment, either the Royal Scots Dragoon Guards for Cavalry or the London Guards (originally the London Scottish) for Infantry, as the Blair/Brown administration killed off the other Scottish regiments. The coats were part of the appeal! (The chief reason I didn't pursue it in the end was a change of degree, which had required re-starting and then by the time I graduated I figured I was a bit too old to go for Sandhurst. A regret, to an extent.)
