Materials vary by listing: many women's racerback tanks list a tri-blend of 50% polyester / 25% cotton / 25% rayon, while some options use a 60% cotton / 40% polyester blend.
Follow the listing care guidance: machine wash cold (inside out) with similar colors. Recommended drying is line dry or lay flat to dry for best results; tumble dry low is listed as acceptable. Some product bullets specifically state: "Machine Wash, Line Dry or Lay Flat to Dry."
They are described as racerback tank tops with a crew neckline and a sleeveless (tank) style.
Product details list the length as "At Hip" and indicate single-layered construction for the garment.
The tanks are described as lightweight. Listings also describe the light cotton/polyester material as very soft and thin.
Common wording includes "It's so Fluffy" on several Agnes designs; some juniors' tanks use "Unicorns Are My Spirit Animal."
