I ordered an XL, being between a size 14 and 16 (closer to 16 today...thanks Christmas cookies), and the coat was a perfect fit.  It is warm, rain repellant, not excessively bulky, and has slit pockets, as well as zippered pockets, to keep my hands warm.  One star off for a one-way zipper (need a two-way zipper for this coat length) and unlined cuffs.
