Short shoulder volume and large flowers sit beside each other in this complete front. The short sleeve areas create rounded upper sides. Larger flower and leaf motifs spread across the pale garment and wide skirt surface. Noticeable head and ear ornaments add further detail. Several different properties may therefore account for your preference. Choosing the side sleeve outline need not mean choosing every large motif and accompanying ornament in the same photograph as well.
Look initially at the route from shoulder to exposed arm. Do you like that short upper fullness? Compare a similarly short form on a quieter surface afterwards. This keeps sleeve shape distinguishable from the larger pattern. Both can appeal, but naming them separately makes it easier to find a real candidate that satisfies your main preference.
At a fitting, begin with arms relaxed and skirt falling normally. Add head details and jewellery afterwards. The photograph cannot establish manufacture or material. Ask about the actual garment and assess its selected shape beside your intended accompanying pieces. The broader lower surface remains another volume decision rather than a necessary consequence of liking the short upper contour.
