A very low back is emphasised here by a pale edge extending well downwards. The remaining visible garment surface stays relatively quiet. A noticeably decorated area sits at one shoulder, with a sleeve resting beside the chair. The wearer turns the head and torso to the side. The main idea is the contrast between a large open area and a quieter surrounding surface. This view establishes neither the entire front nor the internal arrangement, and its pale slightly greenish colour impression proves no particular fibre.
If this depth appeals to you, compare it first in a natural standing posture. Lower your arms and walk a few steps before sitting. Ask about the construction intended for the actual offered model. Then obtain a full front view and decide about both sides together. The strong rear outline can be compared with quieter jewellery while retaining the shoulder accent. Try the planned outer layer too. This keeps the unusual depth as a deliberate design preference without treating the turned seated pose as a sufficient explanation of the complete dress or its fit.
