Trend Alert?- women's westerns

Women's westerns doesn't mean cowboy shirts it just means a button down shirt. I've seen these around campus alot today. For example my retail class is 60% girls. 1/3 of them (including me) was wearing so kind of women's button down. They come on in short sleeve, long sleeve, cotton, different colors, patterns and the most popular- denim. My favorite way to wear mine is with dark jeggings (or leggings). Another way to wear them is tucked into a pencil skirt. Are these women's westerns going to be a trend for fall? Or just a fad right now
