White butterfly motifs extend across a close upper shoulder area. Larger and smaller wing shapes stand away from a finely sheer-looking surface in places. Skin remains visible between them. A narrow strap line and finer horizontal folds appear alongside. A larger pale folded area sits at the lower part of the crop. The head is cut off; hands, a complete lower sleeve ending and skirt length are absent. The image therefore particularly supports comparison of individual motif positions.
Follow the wing edges and spaces between them. Some shapes sit nearer the outside of the shoulder and others towards the centre. You can show that distribution as a preference without converting it into a particular sleeve type. An entire loose or fluttering arm contour cannot be traced here. Request a supplementary view of the same model for that question.
The decoration actually described for the candidate matters too. Ask about material, connection and included pieces if those details remain open. This close view shows visible relief rather than a reliable manufacturing explanation. Record the wanted motif separately from unseen construction details.
