Dresses can certainly be stylish and casual at the same time. Most everyday dresses are just more comfortable than more formal dresses.
These sorts of dresses are certainly versatile. Some people might decide to wear casual dresses to events and parties. Even if the event itself isn’t especially casual, the outfit could still work.

People will want to be comfortable during that celebration, and a dress that’s relatively casual might make that easier.
Many casual types of dresses have short sleeves. People often wear these sorts of dresses when it’s warm outside, which makes that sort of design popular.
However, there are also lots of casual long-sleeved dresses. These sleeves might be relatively loose, making the dress more comfortable. Rolling up these sleeves on these dresses should also be comparatively easy. People might assume that a dress that was designed to be worn casually will be shapeless. However, a lot of these dresses have belts, sashes, and other features that will automatically give them more structure.
Casual new dresses tend to be fairly loose, at least in part. Many of them also have floral prints or similar designs. These dresses will make people think of the outdoors and sunny days.
