The visible elements match the description:
Velvet Shirt: The deep navy blue fabric has the characteristic sheen and drape of velvet, and features heavy, intricate "antique work" or embroidery on the square neckline, daman (hem), and sleeves. This type of work often includes metallic thread (like zari or tilla) and sometimes sequins or beads, which is popular in South Asian traditional formal wear, especially for winter.

Shisha Silk Bottom: The matching wide-legged trousers have delicate embroidery on the ends, consistent with the description and typical of an elegant silk or shisha silk fabric.
Organza Silk Dupatta: While the dupatta is partially draped and its full detail isn't clearly visible, the overall flow and lightness of the fabric over the shoulder suggest it could be a sheer organza silk.
