Gathered sheer sleeves create a longer area between patterned shoulders and narrower wrists here. Larger floral forms concentrate on the bodice, leaving quieter transparency along the arms. Both hands are held slightly sideways. This separates the sleeves from the body and makes their folds easier to see. The photograph describes an arrangement; its specific fabric name remains a question for the actual offer rather than a conclusion drawn from the image.
Choose how much area you want around the forearm first. On a real candidate, lower the hands and then reach for an object. Where do the folds gather afterwards? Would you combine a patterned shoulder with a quieter sleeve or continue more motifs along its length? Keep those preferences separate.
Compare the confirmed sample within the intended sleeve construction, not only over the skirt. Desired transparency there need not match the bodice. Introduce your bracelet afterwards and inspect its distance from the lower finish. The chosen combination should work around your own hands rather than only in a sideways photographic pose.
