Mechanic t shirts are one of the few designs we wouldn’t recommend wearing for work. The nature of this line of work doesn’t allow for a dark design on a light mechanic t shirt. You can, of course, order a custom design of white print on a dark t shirt from us, but we recommend using our mechanic t shirts after work, when people don’t see you in the shop and know who you are without reminding. You can promote your business by adding a company logo or just by representing yourself through what you do.
