Crew necks are the most common neckline across short- and long-sleeve pajama tees. V-necks also appear, particularly on relaxed sleepshirts and some casual styles.
Most listings show lightweight to midweight fabrics. Some pieces are labeled or described as suitable for year‑round wear, indicating a midweight or versatile construction.
Common sleeve lengths include short sleeve, long sleeve, three-quarter (3/4) sleeve, and sleeveless styles.
You'll find regular and casual fits as well as relaxed or slightly fitted silhouettes. Some styles are cut longer for a relaxed, draped look.
Sizing is shown via size charts and fit notes. Some listings say the garment fits true to size, while others note it runs small (recommend sizing up) or suggest sizing down for a more tailored fit. A few listings also offer extended sizes such as 1X–4X.
