Many maternity henleys are made from 100% polyester knits. Some styles use blended fabrics — for example, 63% recycled polyester, 33% rayon, and 4% spandex — to vary the feel and stretch.
Several maternity henleys include built-in nursing functionality, such as henley-style snap plackets or easy snaps and a double-layer fabric over the bust to provide coverage while breastfeeding.
They commonly use a Henley or split neck with button detail. Some styles offer scoop necklines and henley-style snap closures for easier access.
Design details such as flowy babydoll cuts, high-low hems, split-neck or Henley styling, and soft fabrics make these tops easy to pair with leggings or jeans and suitable for everyday wear, the office, casual gatherings, or baby showers.
Coverage varies by style: some henleys use high-low hems to ensure full belly coverage, while nursing-focused designs include double-layer fabric over the bust for added coverage during breastfeeding.
