Rounded back with patterned borders provides the softer comparison to the pointed V. The person stands with the back toward the camera. Broader patterned shoulder sections travel down the sides and approach a low, rounded-looking ending. A decorated waist area sits beneath it, followed by a wide pale skirt. The pattern occupies more visible space at the sides than in the narrowly framed V example. The differences concern the outline and the distribution of decoration.
If you like this version, ask at the fitting for a soft lower curve and show the border width you prefer as well. The phrase low back alone would not describe those two wishes clearly enough. On the actual model, compare where the opening ends against the skirt start and how the decoration continues there. A possible fine intervening layer cannot be reliably identified from this photograph. Request an explanation of the middle and a look inside rather than inferring construction from visible pattern width. The wide pale skirt provides a setting for the rear-line comparison, rather than evidence of a particular material.
