The pearl jumper is written in ENGLISH only using US terminology. The pattern is super beginner friendly, there are detailed steps and photos throughout.
It is a made to measure pattern, this means you take your own measurements as instructed first, this means it can be made for any size and age.
You can make it simply as a jumper or a jumper dress, some testers also did short sleeves.
You will need any type of light worsted weight or DK weight yarn in any desired fibre and a 5mm crochet hook. I used roughly 1200m of yarn for the sample size (UK 8). This was for the jumper dress style (grey one in pics).
