I Know What I’m Doing

The results speak for themselves. The process has declined to comment.

“I KNOW WHAT I’M DOING. I JUST DON’T KNOW HOW I DID IT.”

The How I Did It Tee is for anyone who successfully got something working and has wisely decided not to investigate any further. Whatever happened worked, and attempting to understand it now could only introduce unnecessary risk.

Perfect for accidental experts, problem solvers, improvisers and anyone who has ever fixed something and immediately become afraid to touch it again.

Foolproof by design.

Reproducibility not guaranteed.

Our suppliers provide these measurements. Note that there might be a discrepancy of up to 2 inches (5 cm).

Helpful hint: Compare these measurements with a similar item you own by measuring it at home.

A Length

Start measuring from the base of the collar at the top of the garment (at the highest shoulder point) down to the bottom edge of the item.

B Width

Measure from one side seam under the sleeve across to the opposite side seam.

C Sleeve length

Begin at the middle of the back collar, extend the tape along the shoulder seam, and follow down to the end of the sleeve cuff.
