Duberess Women's 1 Hooded Sweatshirt

How do I know what size to choose? I am 5'4 and weigh 155. Which size is smaller, the one size or xxl?

I just ordered the green one and it came with a very heavy corduroy hood and green pockets. Do they all come that way?

Does it fit if the height is 5ft?

I love the corduroy but which ones have corduroy other than green?
