open back tank top

Common necklines include scoop and crew necks, V-necks (including deep or plunging V-necks), and racerback-associated scoop shapes. Wording varies by style, but these are the most frequently seen neckline types on open-back tank tops.

Coverage ranges from opaque medium-weight knits to sheer mesh. Lining options vary by style and include unlined designs as well as double-lined or layered styles that provide extra coverage.

Adjustable and fastening details include tie-back straps or neckline ties (often thin), elasticized empire or waist bands for stretch and fit, and sometimes non-slip clear silicone trims at the neckline. These features vary by style to allow fit adjustments or secure the top.

Listings commonly use labels such as Women’s or Juniors, with numeric sizes shown on many items. Available numeric sizes often range from XS up through XXL on at least some options, though exact ranges vary by brand and style.

Common back designs include racerbacks, split-back styles with ties, lattice or cross-back string details, open V-back cuts, and backless or halter-style openings. Style names and exact detailing vary across designs.

Materials include polyester–spandex blends (for example, 96% polyester/4% spandex), cotton–modal blends (e.g., 60% cotton/40% modal), modal or modal-containing knits, rayon–cotton mixes (80% rayon/20% cotton), and nylon–spandex blends (examples shown as 75/25 and 79/21). These blends offer varying stretch, drape, and comfort.

Typical fits include slim, regular, and classic. Lengths are often described as ‘at waist,’ with some styles listed as longer (such as ‘at thigh’) or as crop-length options—availability depends on the specific product.

Open-back tank tops come in lightweight and midweight fabrics. Breathability is provided by sheer or diamond-print mesh and by lightweight technical fabrics designed for airflow; the degree of breathability depends on the material and construction.
