Waterproof A-Line Rain Jacket

I should be a large according to size chart but bought a medium bc I want this so bad as the large was sold out. I am a 8-10 usually due to large chest and medium still fit fine. What I didn’t like is the bottom is flared out sorta like a trapeze cut which is not reflected in pictures. Also it smells so bad like a super plastic my smell. The quality of the jacket is high and the olive color is pretty. I will be returning bc I don’t like how it flares out at button.

The first time I wore the coat and unbuttoned the coat, a snap stuck together and was pulled out from the coat. A day later it happened again with another snap. I did not pull on the snaps with any greater force than I have done with the other snaps or with other coats. It cannot be repaired. I am disappointed and will bring it back to Nordstrom.
