"Trust Me, I'm a Mechanic" T-Shirt | Funny Gift for Mechanics
Size Guide
Find your fit
All our gear is built on classic-fit Gildan blanks — true to size with a comfortable, not-too-slim cut. If you like room to move (or you're layering over a work shirt), size up.
Since everything is made to order, we can't accept returns for ordering the wrong size — so take a minute here before you buy. When in doubt, measure a shirt you already own and love, and match it to the chart.
How to measure
- Chest: measure under your arms, around the fullest part of your chest.
- Length: measure from the highest point of the shoulder straight down to the hem.
- Compare to the charts below. Between two sizes? Size up for a relaxed fit.
