NENONA Women's V-Neck Button Down Knitwear Long Sleeve Soft Basic Knit Cardigan Sweater

So is this more casual than it looks? Like a sweatshirt or nice for the office?

I have the black one and I love it but it collects hairs and fuzzies so bad I can never wear it. Anyone with with other colors have this issue??

Description is vague: Cotton Blend. What percent is cotton and what fabric is remaining percent?

I’m 170 and 5’3” go with a medium or large I like it to fit just right on me
