“Dori, Nori, Ori, Oin, and Gloin were their names; and very soon two purple hoods, a grey hood, a brown hood, and a white hood were hanging on the pegs, and off they marched with their broad hands stuck in their gold and silver belts to join the others”
J.R.R Tolkien, The Hobbit

Vest is designed to be worn open and to close only when stretched over your chest. Choose your size based on the given measurements of the garment. If you want it to close choose the size closest to your chest measurement. Seed stitch grows quite a bit and if you choose a yarn that blocks well you can “fine tune” your fit when you block. The model is a small/medium and the vest shown is a medium/large
