Hello. Does this make sense? I feel a comma belongs in statements like, "She had long, curly hair" and "She held a long, straight dagger in her hands" (given that in both examples the adjectives are equals in the conventional category of length and shape), but I don't feel a comma is needed in "She is wearing a short tight dress," because to me "tight dress" seems like the head noun in that one. Is that consistent, though, or is it that the commas are superfluous in the first two examples? Thanks.
