A fitted cotton jacquard blouse with a lace Peter Pan collar and tiered leg-of-mutton sleeves. Rows of small ruffles divide the full upper sleeves before they narrow into long cuffs.
Yilia identifies the material as cotton jacquard. Blouse only; the JSK in styling photographs is not included. The source separately lists 3XL bust 106 cm and waist 90 cm.
The sleeve shape is the defining detail, so a sleeveless dress shows it best. The woven stripe and small raised motifs provide texture even in a single-colour coordinate.
