Okay, so this is a legit down jacket, good loft, and 10k waterproof, this is a great find for the price. As for sizing, It is not super baggy, and not super long, but it is larger fitting than most down jackets. If you are looking for a really long down jacket, check out Orage B-Dog. I went with XXL and I am 6'2, 210lbs (not fat, but not a string bean), and it fits me perfect for a look that is in between Quatro XL Down-to-the-knees Park jackets, and Skin tight Cross country skier fit. It looks SICK too. This is a stylie jacket by all means, and fully functional. I will get a photo on here of me in it soon.
