Leaving aside the length, I think that if it was a little higher the aprons would lie more smoothly - the kilt looks to be forming slight folds, which would indicate that it was a little strained at that point.

From decades of fitting costumes, the cure is to lift the garment above the horizontal folds and ensure that the vertical shape is not distorted. That might result in several alterations, but a straight all round lifting is the one to try first and see what happens.
