So we recently made a Gene Wilder Willy Wonka outfit for me. The hardest part I found to replicate (as many others probably have too) is the glorious vest that he wore. I am doubting that there is any material identical to it out there. Here is the next best thing (IMO).

I found a high res photo someone had taken of the vest at an auction. I was able to see a spot in the pattern where it repeated. The area was then cropped and made into a repeating rectangle that could be used to print. Did some color and brightness correction as the original picture looked to be in low light. Here is a comparison.

Now that we have had it for a few months, we thought we would share the pattern on Spoonflower. Hope this helps others who have ran in to this problem.
BONUS
We had enough vest material left over that we decided to make a "fun" cosplay. Check out my Willy-Won Kanobi!!

We used crushed purple velvet for the robe, the tie material for the lining of the tunic, and a belt that matches the color of the hat.
