Wow, $140, what a steal!!
The fit is perfect in my opinion. I thought it would be a little tighter since it is one size smaller than my "winter" Bedale SL but this new one doesn't have... how do I say this in English? Lining? Not having it makes it bigger, loser so it fits great to wear with a shirt and even a light sweater.
Sizes in Spain are different in regards to suits so I really have no idea the equivalent but I wear a 52 size jackets (sometimes a size 50 depending on who makes them). On my regular casual jackets I wear a size M but if it is a peacoat I use a size L.
Anyways, I hope this helps.
Sorry for the delay answering your questions.
