The sultan of fit is right, as always. I think the sleeves are a tad long, but at the initial price, I wouldn't bother shortening them. Doesn't H&M have a policy of selling jackets and trousers as separates? If so, I'd run like the diarrheous wind and buy the trousers as well. You'll get a useable jacket, useable separate trousers and a well-enough-fitting expendable suit. And the jacket is begging for a crisp white shirt.
