18 inches is short to wear crossbody; I wonder how the seller is measuring it. Mine measures 20 3/4 inches to the top of the bag (not the handle). The top of the bag hits me at the top of my hipbone when I wear it crossbody. I'm 5'4." The original ad says 44 inch strap. It's closer to 45 inches if you include the clips.Is this strap long enough to wear cross body? I know it says 18 inches, but that doesn't help me picture it.
