I thought that it was fairly shameful that the Yahoo! Style staff, who apparently all wrote this caption, didn’t know that each is a singular noun and that are wearing was the correct verb to go with it:
But then I read a few more words and realized the staff writers were pulling their readers’ legs! They were joking! Because nobody would seriously write that each model was wearing four jean styles. How would they even put on four pairs of jeans? I’ve never managed to pull on more than two at one time.
