In fear that I might pop a button, no breathing or eating can be done once buttoned. Honestly, I won’t even wear the jacket buttoned because it looks like it doesn’t fit. All double breasted jackets/coats tend to be smaller, but I’ve bought one from FN because and it was actually loose, but this is not the case. Quality is decent for the price. Jacket has some weight to it. Bought the full suit, pants fit great.
