Need help with a jacket I found

So i found a converse jacket/blazer style in Target today. It's $50 currently. Though I tried on a small and medium size and neither seems to work too well. The small restricts my movements if I go to bend over, while the medium feels too big on me. Can I get r/MFA's opinions?

Also, is there a place I can find a similar style/better style jacket for about the same price?

Small size, Medium size -- I rolled up the sleeve a bit, because it seemed too long without doing so. How long should the sleeve be when I extend my arm out?

Edit: Alright, I'm glad I didn't get that jacket. Though I am looking for something similar in color and rough material. Where should I begin looking?
