How do I determine the correct female clothing size as a male?

I’m a male, 17 years old, 5 feet 11, fairly slim, weighing 120 pounds.

My chest size is around 36 inches and I wear men’s medium shirts.

I’m looking to purchase this junior sized hoodie:

But i’m not exactly sure if this will fit with my height.
