Casual wear is typically the dress code in which new forms of gender expression are attempted before being accepted into semi-casual or semi-formal situations. An obvious example is masculine jewelry, which was once considered shocking or titillating even in casual circles, and is now hardly noteworthy in semi-formal situations.
Amelia Bloomer introduced trousers (of a sort) for women as a casual alternative to formal hoops and skirts. In a recent mirror image, sarongs and other skirts have been embraced by a few men of the European tradition as a casual alternative to formal trousers. Both of these innovations caused great embarrassment in formal circles.
Skin exposure is most pronounced in casual wear, since it includes all swimwear, but the trend toward female exposure in the 20th century has also pushed the necklines of formal ball gowns ever lower and the skirts of semi-formal cocktail dresses ever higher. For men, the exposure of shoulders, thighs, and backs is still limited to casual wear.
