I have gone from 311 lbs to 265 lbs in the last year. I ordered a wool overcoat jacket on clearance from Men’s Wearhouse in an XL since the AI said that’s the size I should get. It is perfect in the length and the sleeves but snugger in the chest and stomach areas. I can’t button it however it doesn’t look super tight. Is this acceptable? I can’t exchange it since it was a final sale. Did I shoot myself in the foot?
