Sizing — read this before you order

All sizes displayed on my site are in standard North American sizing. 

Countries such as Japan, The UK, Australia and others do have their own sizing standards. Please use the information below to choose the correct size.  

Straight up — I can't do returns or exchanges on sizing. 

I say that because International shipping and tariffs make it impossible for a shop my size. A size swap to the other side of the world costs more than the shirt.

BUT, I will work with you to get the right size you need. Just reach out!

Let's get the size right...

TIP:  These are genuine work shirts — grab a shirt you already wear, measure it flat, match it to the chart. Takes thirty seconds and it's the most reliable way to do this.

Still not sure? Send a message before you order. You'll get me — the gearhead who drew the thing — not a AI bot. I'd rather spend five minutes sorting your size than have you stuck with a shirt that doesn't fit.

So ask, I'm here to help.

Clothing sizes:

If you are unsure about your size, please consult either your closet, your mom, your wife, or as a last resort, our chart below. If you wear a large shirt from Walmart, you will wear a large shirt from us.

And yes, unfortunately, 2xl, 3xl & 4xl costs me more, so I do have to charge more for those.

All my clothing sizes follow standard North American apparel sizing in INCHES and the guides below are approximates based on manufacturers specifications.

Width measurements (unless otherwise noted) are measured in CIRCUMFERENCE in INCHES

Tee Shirts

Most men's tees are cut pretty much the same. Measure a tee you already own, flat, and match it to the chart on the product page.
