Outlined bodice sections form two clearly drawn areas beside a long narrow receding centre. Decorated straps pass over the shoulder while the arms remain bare. Pale floral lines continue through waist, hips and the lower flared skirt. Hands hang at the sides and obscure little of the front. This makes a useful comparison with an off-shoulder sleeve start: the upper arrangement remains visible, but its connection follows another route over the shoulder top. A clearly drawn frame is not evidence of a particular internal support system; it describes only the visible surface and connection.
Compare those two routes first without treating the outline as a technical support result. Photograph your real candidate relaxed from front and slightly to the side. Decide whether you want a continuing shoulder line or an open upper transition with a sleeve beginning lower down. Assess the hands afterwards: much of the forearm remains bare here, unlike the space beside long floral-looking sleeve edges. Your own jewellery test can clarify that difference. Rear strap direction, fastening and possible alterations need information about the same real garment; this front view does not establish them.
