I got a 4XL hoping it would give me extra room since I'm more of a 3XL/XLT body type. The width ended up being more than I wanted and the length didn't match the width. As a result, it was hard for me to keep the shirt tucked in properly during moments when I bent over or moved around my torso a bit. Perhaps I should have gotten a 3XLT instead, but while the shirt was fine for quality I didn't really like its dimensions. It's also nothing close to luxurious feeling, so if you're looking for something that is smooth and upscale then this isn't your shirt. I probably won't use the shirt again since I don't like the fit I have and I'm not a frequent formal attire wearer.
