I took exact measurements, which directed me to the 2XL blazer. This seemed odd as I have never been a size 2XL, but I wanted to follow the size guide. Unfortunately, it's too large so I had to return it. It was beautiful though. Currently all tweed blazers are sold out in my actual size, so I cannot have a Kirrin Finch blazer at this time. I hope the XL tweed blazers are restocked, I can't wait to re-order!
