Not speaking for the parent commenter, but I imagine "casual" as roughly the same range as "preppy" - not formal, but not sweats or tshirts. Also, while they used the term "skater" (which I also find oddly specific) I think "streetwear" would be a better label. This would cover more specific styles like "skater" as well as other types of streetwear. As a disclaimer, I know next to nothing about fashion and am just going on my own limited perception of broad categories.
