Personally i like the gauntlet sleeves the best, but get what you like the most as you will be the one wearing it.

As for sizing, check out a few sites for their measurement instructions:

If you go with J.Higgin's argyle, I would suggest seriously considering getting the waistcoat as well. If you think you may wear it, it is going to be a good investment for an extra $60 http://www.jhiggins.net/sf_proddetai...181C0C0OQSP9FD

If you decide to order one in the future or from another supplier it may not be an exact match with the jacket.

Good luck with the purchase, I find that an good kilt jacket just completes the look.
