Green Chartreuse Knitted Cardigan Pullover with Large Collar, Long Sleeve

There are no tags or indications on what this sweater is made of or the size. But it's from my sister's closet who was a bitsy thing so I'm going with a size S. Please refer to the dimensions provided below. Also, no indication of the type of fabric but it feels really soft!
