Congratulations on a very serviceable kilt jacket, good job!

The sleeves look a little long. Standing as you are in these pictures, a little past the bend in your wrist is good. All the way to your knuckles it a bit much.

I personally find changing the sleeve length on a jacket a bit tricky to get a good job on, but not impossible. If you do decide to shorten the sleeves a little, and it gets too daunting, it is a very standard alteration that any tailor can help you with.

Enjoy your fine new jacket!
