A side-waist cut-out creates a clearly visible opening between the upper and lower dress areas in this view. Fabric continues at the front and reaches high around the neck. Shoulders and arms remain bare. Below the defined middle, a long skirt opens through a high side slit. Small reflective details are densely distributed across the pale surface. Open strappy shoes complete the front view, which therefore brings several different exposed lines together.
For a fitting, separate the waist opening from the other open areas. Do you specifically want that side space visible, or are you mainly drawn to the high neck and bare shoulders? Try similar real candidates with colour and underwear reasonably consistent. Inspect the opening with relaxed arms first, then while reaching.
Walk and sit before rearranging the fabric. Assess the slit as its own decision and request a rear view. The front photograph does not explain every back connection or inner layer; ask to see them on the actual garment. The visible opening becomes a targeted shape preference without requiring you to choose all the decoration and the pictured leg opening automatically as well.
