The pattern instructions are clear and the finished jacket fits very nicely. All the details (especially in the collar and cuffs) are very clean and create a professional, tailored looking jacket. My only downside to the pattern is that it is not size inclusive. I made this for my husband who has a chest measurement of 42" and I needed to make the largest size in the pattern. My husband is average size and typically buys size large for his tee shirts and jackets here in North America. So having to make the largest size available and knowing that there is no larger options is quite surprising to me. I would be happier if there was a larger size range to fit the majority of men.
