I'm getting the hang of painting the British (sheesh, it only took 20 or so figures!) and have evolved a style that is quite pleasing while retaining enough of the heavy lace detailling that I think can be a bit off-putting when approaching them for the first time.
I've tried fairly hard to differentiate them from the 44th Foot by giving them nice, smart, white gaiters and left them with laced, red waistcoats. Note that they also sport lace "wings" on their coats. These were surprisingly easy to do and look pretty effective.
