This jumper is worked top-down. You may therefore adjust the length to suit your preferences exactly.
It is meant to have a snug fit around the chest. If your measurements are 1⁄2 - 11⁄2 inches larger than a given
size, you may very well knit that size. The yarn is soft and yielding and willing to wrap your body, and the jumper looks good with a close fit at the top.
As example if your chest is 91-95 you can choose size 38 (UK12) where the actual chest measures 86 cm.
