连衣裙，又称连身裙、袍衫裙，是指上衣和下裙相连的服装。

在中世纪以前．西方大多数裙子属于连衣裙，到了16世纪以后，上衣和裙子就逐渐分离开了。第一次世界大战之后，妇女服的主流仍然是连衣裙。连衣裙的种类也就变得多种多样。

中国古代的深衣，其上衣与下裳（裙）相连，也可以看作一种连衣裙。

A dress (also known as a frock or a gown) is a garment consisting of a skirt with an attached bodice (or a matching bodice giving the effect of a one-piece garment). In Western culture, dresses are more often worn by women and girls.

The hemlines of dresses vary depending on the whims of fashion and the modesty or personal taste of the wearer.
