If you have old clothes but don’t wanna throw them out, try to remake it and you will get new things! For this DIY you will need a 22 inches zipper, an old t-shirt or 1 yard fabric. For this zipper you will need another side so pry little stoppers off the end and pull another zip through, you’ll get double sided. You can use an old t-shirt. Cut the neck ribbing and shoulder/sleeve seams as shown on pics. You will probably have to cut the sleeves to fit with the length of the zipper or adjust the zipper length if you don’t want to finish the sleeves again. The rest of the tutorial is here.
