This is a crochet pattern - instructions on how to make this jumper. It consists of a written pattern, with videos and photos to aid. It's made to measure, so you make the jumper based off of your own measurements. I recommend using a 5mm hook & aran/dk yarn. It's quite a large pattern & theres a couple of fiddly bits but I've made it as beginner friendly as possible. Am happy to answer questions / further explain things too if needed :)
