Love this blazer. Sleeve length was perfect, as was fit in waist and bust. Shoulders are on the big side, but not too noticeable. Fabric and construction quality are very good. There's also a little hide-y pocket inside that's big enough for keys or a small phone. I wore it with jeans, but think it would go nicely with a navy trouser. Also wore with the KF lavender dress shirt and Astair bowtie.
5'7", 169 pounds. My KF shirt size is 10, which fits really well.
