I have a medium, and it is 27" from the hood seam (at the collar) to the bottom of the jacket.
To answer your question, I would need to know your size, but I usually wear a 10-12, which is large. The rain jacket size lg. fits perfectly with a bit of room to spare. You can tighten/loosen the wrists, waist, neck. Lightweight, breathable, and a very good rain jacket. Length is to bottom of butt. Plenty of coverage.
