Adidas Neo oversized striped sweater

I fell in love with this sweater when I saw it online but didn't realize it was oversized. I'm 5'1 so it makes me look way smaller than I am. Not flattering for me at all. My boyfriend bought it for me for Christmas since he knew I liked it so I wasn't able to return it. It's NWT, never worn. It would be perfect with leggings in the fall and winter. It's not a super thick sweater but it isn't super thin either. It will keep you plenty warm without making you sweat!
