Men's button down dress shirt sizing guide (up to 3XL)


Why size matters! (when it comes to your clothing)

Getting your fit right will make or break how people (and you) feel about what you're wearing. If your shirt is too tight, at the very least you'll be uncomfortable and at the worst, you could tear it or pop a button. Too large and people will think you borrowed it from your older brother. 

Contemporary vs. Slim Fit:  What's the Difference

If you like a more form fitting shirt and have a narrower frame, the slim fit would best suit you. If you're in love with a  slim style but don't have a slim build, we recommend sizing up one or maybe two  to compensate for the difference.

We engineered the shirts to be worn untucked so you probably won't need to worry about the shirt getting too long even though you've sized up.
