The blue strapless front begins with a relatively horizontal upper edge beneath bare shoulders. Crossing diamond-like lines spread over a closer long front area. A longer opening sits over one leg. Broader pale blue areas extend at the sides and behind. Pale pointed shoes show through the opening. Both arms lead down beside the body. Loose wavy hair lies more heavily on one side of the fully included head. The background provides no material description or confirmation of included pieces.
Compare the upper frame with the diagonal main reference first. Then ask whether you want crossings over the whole surface or a quieter middle. Broader side areas are another decision. Their visible route does not establish separate attachment, removability or supply as an independent piece.
Request both sides and rear of the same offered version. Try the opening while seated and during a step. A drawn grid does not explain how the actual area behaves in your movement. Keep the wish for a strapless edge separate from the wish for additional lower width, rather than letting this single photograph settle both.
