The inspiration for this DIY came from this Theory Blazer. I love the addition of leather sleeves on to a classic shape. A grey blazer that I never wear (too blah) and a thrifted leather jacket (way too big) made the perfect starting points.

|[Using a seam ripper, remove the sleeve from the blazer. Leave the sleeve lining intact]|
|[Separate the seam on the blazer sleeve and open it up. Cut off the sleeve on the leather jacket and open it up. Use the blazer sleeve as a pattern piece and cut out a new sleeve in the leather]|
|[Sew the sleeve together at the side seam]|
|[On the inside of the blazer, at the bottom separate the lining from the body. This will give you access to the arm hole]|
|[Sew the leather sleeve on to the arm hole. Slip the original sleeve lining inside of it]|
|[Sew the new sleeve to the lining at the cuff. Repeat steps with the other sleeve]|
