This pattern is written for ANY GAUGE of yarn for ANY SIZE. You choose yarn you want to use. You measure your own body (that makes it just for you) and knit to that size. All the math is set out for you step by step. You are the boss of this pullover.
Knit it in one colour, with stripes or add a Twisted Stitch pattern (in the Mods pages). Add extra Bust Shaping or Extra Wiggle Room for your Hips.
