Size Guide
Size guide
Every body, every alien, every vibe. Our tees come on three different blanks and they fit three different ways, so the chart on each product page is the one for that shirt. All measurements are in inches with the garment laid flat; double the chest number for the full circumference.
Not sure? Grab the tee you already love, lay it flat, measure armpit to armpit and compare. We'll wait.
How to measure
Lay it flat. Three numbers.
Chest: armpit to armpit, straight across. Length: from the highest point of the shoulder, next to the collar, straight down to the hem. Sleeve: from the center of the back collar, along the shoulder, to the end of the cuff. Hats and beanies are one size and adjust; totes do not care what size you are.
