The bodice with skirt panels creates a clear change in the scale of the surfaces. Narrow vertical lines and small web-like motifs cover the upper section; larger pale outer panels sit below. A patterned area appears again inside the front opening, providing both contrast and a repetition of finer drawing. The visible join does not establish that the garment consists of detachable separates.
If you like this arrangement, request a fitting view with the panels hanging freely. The hand position in the photograph may influence how far the opening spreads. Then take an ordinary step and notice how much inner pattern appears. This helps you choose a relationship between quiet and patterned surfaces, rather than concentrating only on the height of a slit.
The broad, densely decorated necklace creates another strong area around the neck. Compare a similar outfit without it if you want attention to remain at the waist. The broad shoulder straps add quieter pale lines of their own. For your decision, examine neck, bodice and outer panels together in a full-length mirror before choosing which extra detail to add.
