Champion Men's Reverse Weave Pullover

Do these hoodies shrink after machine washing and drying? If so, vertically, horizontally, or both?

I‘m 5‘5 and 145 lbs should i take s or m? the hoodie should fit a bit loose...

The reviews for this are all very different some say it’s great and some say don’t buy it is this a real champion hoodie ??

There is no champion logo? This is very concerning and makes me wonder if it is a knock-off. Please reply soon, this is unacceptable
