Long hair in TS4 is medium hair to me. Long hair to me is hair is what we had in TS3, that is close mid-back length. Like the picture below which is of a base game TS3 hair (I believe it was base game). Why don't we have that in TS4 ? Of course there might be clipping issues with clothes, but there are some already in the game. Some hairs like the straight hair with bangs from Cats and Dogs are longer at the back but the front part is short. It's still nice though.
