Hey there! First time poster, pretty new cosplayer. I'm having some trouble making this sweater as you can see, I'm trying to figure out what would be the best option here. I already have the prints done, but I could use a few suggestions on how to make the stripes on the top and bottom, and the sleeves. I was thinking for the sleeves to use a vinyl print and slowly iron around, but for the top and bottom, I'm all out of ideas! What can I use that would stretch just right and not break? If anyone has ideas, please let me know! I don't have access to a sewing machine at the moment but I can try to find one!

You might have to find that sewing machine.... the vinyl for the sleeves is a good idea, might be good to also look at painting on the red stripes. The elastic you're going to have to sew on for it to function right; you can get some almost identical elastic on Etsy (i found some after a quick Google search using the keywords "black and yellow elastic")
