Broad straps at an open back form longer, vertically drawn-looking areas in this photograph. A deeply open centre remains between them. Smaller pale points scatter across the upper areas and skirt, while a narrower drawn section defines the waist. The person looks back sideways. The image shows the rear rather than its corresponding front neckline, which needs another view of the actual model. Avoid supplying it mentally from a different dress.
If this rear arrangement appeals, compare the space between the two areas first. Would you leave the centre this clearly open or seek another connection? Lay the intended hair over it once and lift it clear afterwards. This reveals which parts of the drawing will actually remain visible in your worn outfit.
Add the planned veil and assess its edge separately from the small pale points. Ask about the real shoulder-to-waist connection too. A broader visible surface cannot establish support or hidden underwear. Test the garment with your actual pieces and natural arm movements before committing to that rear route.
