I ordered all three sizes to ensure I was getting the right fit. I kept the 2x. The 1x sleeves were too tight, 3x was too big overall. 2x sleeves were snug, but it is a blazer so I won't be wearing sweaters underneath. I reinforced the buttons and it will need tapering to accentuate the waist for me. It will be a good look though. The material is a bit "swishy" but with the right outfit and accessories, it will be fye.

This fits pretty good and it's actually a little roomy for me and I'm pretty stocky with big arms. I am between an XL and 1X so I went with the 1X to be safe and it's good. I have a 38 to 40 inch waist and it buttons with a little tiny bit of room. My bust is about 45 inches and it covers. My only gripe is that the satin is a little wrinkly around the edges so it looks not too high end. But I think it looks better than the pictures online.
