English term (edited): drop back or dropped back (bottom hem)

Fortunately, since I answered a variation of this question almost 5 years ago, so I know what this is. A dropped back, or drop back, garment has a hem that is lower in the back than in the front. And there are certainly more ways than one to express that idea in either language :-)

dropped back bottom hem => dos plus long que l'avant
