Tall and thin old people wear slim down jackets. Down jackets that are too loose, whether long or short, are not good. Because the down jacket itself is inflatable, if you wear version A or O, it will only look looser. Too loose down jacket will make Ang's whole person bigger and fatter, and he looks very listless. Not only can't cover the upper body meat, but it will be fatter. So choose a slim down jacket.
