This isn't your average cotton blazer. If you look closely, you can see that this doesn't have any darts often found on most modern sport coats. They're easy to miss, but the thin stitching that runs from the chest to hip indicates fabric has been removed to nip in the waist for a more tailored fit. But as things get more relaxed and silhouettes widen, this jacket cuts out the darts (not unlike the mid-century American “sack suits”). Plus, it's cut from organic cotton-twill that's been garment-dyed and washed for a rich color and a soft hand feel. In short, this might be the perfect blue blazer for summer.
