Shorten jacket length 3” – 30” centre back
Extend side vents 3” to compensate (Use fabric from belt for seams if need be)
Move bottom pocket flap up 1”
Move bottom pocket up 1 1/2“ (There is a 1” gap between pocket & flap)
Shorten bottom pockets 1 1/2“
I suggest reducing from the top, as it is a straight edge. The flap will then be slightly wider than pocket, so make sure it is centralised with pocket.
All marked with pins.
