A low flare and broad train can be read above the spread rear area of this pale dress. Fine straps and a deep V neckline set the upper boundary. Pattern continues across the hips and the longer closer skirt section. Farther down, the contour moves outwards while a much wider floral rear area lies on the floor.
Treat the close section, transition and arranged train as three visible areas. A very broad rear finish alone says little about how early the front skirt widens. The hand holding yellow flowers also covers part of one side. Request another view without that obstruction instead of supplying a complete contour that the photograph does not show.
At the fitting, put the bouquet down once and check the side with relaxed arms. Walk with your intended stride and sit afterwards. Discuss any preferred change directly on the dress. The photograph does not establish which alterations are possible or how the closer section will feel on you during movement.
