I basically just started with basic hoodies in the colors I wanted. Got them from aliexpress bc I was on a budget, but shipping took too long and I could probably have gone to a thriftstore, but I wanted matching pants. I ordered custom iron on stickers for the airplane & cucumber.
Then I worked on modifying them. I cut one into a crop top, and gave the other open sleeves,and sides. The belts are functional and can be used to adjust the size of the waistbands and sleeve length.
For the letters I used Heat transfer Vinal, and cut them all out by hand using a printed stencil. I highly recommend getting one of those printer/cutters made for doing vinyl decals. However they cost like $80 so I just ended up cutting out the word Cum over and over for 12hrs
But oof yeah that's pretty much it if anyone is interested in making their own. There's also custom print shops online, but none of them had the right colors for the hoodies, or they wouldn't let me print on the sleeve, OR you had to order a minimum of like 10. So I made my own.
