The quality of the shirt is very well constructed. Buttons feel firm and attached well. Sleeve length was good but I wouldn’t call it a slim fit, more of a regular fit. When the shirt is tucked in it creates the "muffin top” effect. Would have given the shirt 5 stars if it was an actual "slim” fit shirt. I have around a 3” fold around the stomach and waist while tucking it in to create a "slim” look.
