Common fabrics include 100% silk, viscose and nylon blends, acetate blended with silk and polyamide, polyester, and modal (including micro/modal blended with spandex).
Silky tank tops are offered in lightweight and midweight constructions; many listings describe them as having a light, fluid drape or a medium/midweight silk‑like feel.
Lengths vary by style: many are designed to sit at the waist or hip, while some styles are cut to fall below the waist.
Both: listings include single‑item options as well as multi‑packs, commonly 2‑packs and at least one 3‑pack option.
Sizes cover typical ready‑to‑wear ranges: some listings offer individual sizes (S, M, L, XL) while others provide broader ranges such as S–XXL.
