About This Design
hypotrochoid tee
Text reads: 'International Institute of Advanced Hypotrochoid Research'. Then at the bottom - 'Peace through continuous contiguity transformations' Remember Spirographs (thats a trademark name by the way which is why we've gone for the correct mathematical term for the shapes oh yes!) - anyway, we loves 'em. So here is a spoof t-shirt celebrating how awesome it would be if we could somehow base a complex framework of peaceful and happy existence on the mathematical laws underlying the hypotrochoids. And it would be awesome. But no, it is complete cobblers frankly - I suspect they will always be used to make pretty patterns - but hey, that's good enough for us.

Value T-Shirt, Black, Adult S
My 11 yo wore adult XL (5’7” 165#). The 8yo is small framed. She wore adult small and tied it in the back. Dark haired male wore adult large and 5’9”, 110# female wore adult medium . Good quality dark Heather gray, Gildan brand shirt. -it was next up from basic choice and cost about $20 per shirt. Not too thick or thin. Washed and dried well, no major shrinkage. Not see-through. Can wear a bra under it fine. Screen print is just as shown and well done, front and back.
