Mino pointed out why I asked the size. It looked like a 44S or something, probably because it was shortened.
This may be a good first buy. It's got patch pockets (which I love) if you like them. They sell your size and you can return it, so if it doesn't fit, there's no skin off your back. I believe return shipping is free.
Don't get peak lapels. Not for your only jacket.
But befre you order, are you sure about your jacket size? you may want to post a fit pic in that jacket and some people can tell you if you should size up or down.
