A sheer back shows scattered floral motifs and a long central row of pale rounded elements. The side transition towards the waist remains visible. A longer sleeve and decorated wrist finish accompany the view. The wearer sits with arms raised, while hair hides part of the upper centre. This is therefore more than an uncovered opening: the translucent surface contributes to the appearance. The exact fastening and materials still need explaining on the actual dress rather than being established by the close view.
Compare a similar surface from an ordinary distance and closer to the mirror. What role should the motifs play, and how noticeable would you like the central row to be? Stand afterwards and lower your arms, checking the waist transition again. If loose hair is your preference, deliberately try its length over the row. Before an alteration, ask whether the middle line or shoulder connection would be affected. This lets you choose a particular arrangement of areas instead of equating its open-looking effect with a deep cut that uses a different construction altogether.
