Broad shoulders around a deep neckline frame the pale front centre of this reference. A broad skirt opens beneath the shaped bodice. The picture makes the relationship between a deeper middle and wider sides especially useful for comparison. You can like that distribution without inferring a particular internal support arrangement or the fibre used. Identify the area you want to retain when explaining the preference at a fitting.
Try the corresponding upper shape with planned underwear. Bend slightly, reach forward and sit instead of only standing front-on. Add a side view and decide how much coverage you want in those postures. If a front alteration is considered, show which patterned area should remain on the real garment and have the possibility assessed there.
Introduce flowers afterwards. Their actual carrying position may hide part of the centre, so compare with and without a bouquet. Request a clear rear view for an online offer too. A convincing front distribution starts your bodice choice; it cannot answer the whole question about fit, fastening and back construction. Those points need their own views and an actual fitting.
