What's the difference between a nightgown and a nightdress?

The difference between a nightgown and a nightdress is mostly about terminology and style, rather than function—they are very similar. Here’s a clear breakdown:


Nightgown vs Nightdress

1. Nightgown

  • Definition: A loose-fitting garment for sleeping, usually worn by women.

  • Style: Often floor- or calf-length, made from soft fabrics like cotton, silk, or flannel.

  • Usage: Commonly refers to more traditional or classic sleepwear.

  • Connotation: Practical and comfortable, sometimes casual in style.

2. Nightdress

  • Definition: Essentially the same as a nightgown; a dress-style garment worn for sleep.

  • Style: Can be similar in length to a nightgown but sometimes implies a slightly more modern or stylish cut.

  • Usage: The term “nightdress” is more commonly used in British English, while “nightgown” is more prevalent in American English.

  • Connotation: Often sounds a bit more elegant or formal compared to “nightgown.”
