Rock. As in "I rocked a new sweater." Please stop saying that. One does not "rock" an article of clothing. One rocks a cradle, a boat, or a stormy love interest. The proper usage in this case is "wear." Example: "I wore a new sweater." If one wants to add a touch of flair to indicate that the article of clothing is being worn in a particularly flashy manner, the term "sport" is preferred: "Sporting a new sweater, a fedora, and a monocle, I was deemed fashionable by my colleagues."
