Yeah, but it basically means it follows the contours of the body it's on. I practically live in oversized shirts, bodycon skirts, and leggings most winters but even when I wear one of the dresses like that,I cover the majority of it with an oversized top. Lol. 
I once told someone "I only wear it so I can get away with leggings and a big shirt with slightly extra butt coverage."  

 Gotcha! Cool.
