If we want to know what a fashion news article is, we should first understand the meaning of a "news article".  According to Wikipedia as of May 24, 2011, here is the definition of a news article:

"An article is a written work published in either a printed or electronic medium. It may be for the purpose of propagating the news, research results, academic analysis or debate.

A news article discusses current or recent news of either general interest (i.e. daily newspapers) or of a specific topic (i.e. political or trade news magazines, club newsletters, or technology news websites).

A news article can include accounts of eye witnesses to the happening event. It can contain photographs, accounts, statistics, graphs, recollections, interviews, polls, debates on the topic, etc. Headlines can be used to focus the reader’s attention on a particular (or main) part of the article. The writer can also give facts and detailed information following answers to general questions like who, what, when, where, why and how.

Quoted references can also be helpful. References to people can also be made through written accounts of interviews and debates confirming the factuality of the writer’s information and the reliability of his source. The writer can use redirection to ensure that the reader keeps reading the article and to draw her attention to other articles. For example, phrases like "Continued on page 3” redirect the reader to a page where the article is continued.

While a good conclusion is an important ingredient for newspaper articles, the immediacy of a deadline environment means that copy editing often takes the form of deleting everything past an arbitrary point in the story corresponding to the dictates of available space on a page. Therefore, newspaper reporters are trained to write in inverted pyramid style, with all the most important information in the first paragraph or two. If less vital details are pushed towards the end of the story, the potentially destructive impact of draconian copy editing will be minimized."

The above listed news article term was obtained from http://en.wikipedia.org/wiki/Article_(publishing) in May 2011.  For the most current information, you should consult with the Wikipedia website. 

In regard to "Fashion Articles", take all of above and add the fact that the subject is regarding fashion.  This can include articles about fashion events, shopping issues relevant to fashion, footwear, handbags, fashion designers, stylists, modeling, etc.  Anything regarding clothing or the apparel industry is fair game.  As long as the article touches on at least one aspect of the fashion industry, the article can qualify as a fashion article.
