TRASH — Bad Decisions Look Better on a T-Shirt.

This shirt speaks to those who fix, tinker, and take pride in hands-on skill. The muted, garment-dyed shade keeps the look grounded and slightly vintage; the heavy fabric and reinforced seams mean it stays sturdy through projects. Sizes span S–4XL so you can find a fit that lets you move freely while you work.
