The white reference places a shorter floral-looking centre between long outer fabric areas. Many broader wavy edges project along those outer surfaces, forming a cascading contour. Additional fabric spreads across the floor below. Broader shoulder connections and a wide front neckline frame the upper section. One hand rests at the waist while the other arm points lower down. Beige closed pointed shoes accompany the visible legs, with both shoes evident in the lower view.
The distribution of width matters for this choice: the centre remains comparatively narrow, while the outer edges extend conspicuously sideways. Compare those features separately from the white colour and pattern in the central area. The impression of a long outer frame explains neither its exact connection nor a particular occasion. A short centre also does not mean that a component can actually be removed.
For a similar candidate, request an ordinary stance with relaxed arms and a complete side view. Observe where the outer edges begin and how far they extend beside the shoe. Choose that visible placement first; actual construction and the right length with your own footwear belong in the fitting afterwards.
