Simply because this is the point of having "Vogue" as the most powerful and stylish brand in the world when it comes to magazines and an ideal of beauty and perfection; it's here for a reason being the bible of fashion which is responsible to set the trends, give a different point of view (more in the most elegant way) and present a knowledge, culture and beauty to a society which before didn't have access to those things, since it was reserved for the super rich only. Vogue's mission is to elevate the minds to what's hot and what's not, and always with a certain glamorous-high end kinda of style, and to push forward the street/casual/sometimes boring plain looks, and to give people the desire and fun to dress up as they present themselves to the outside world. So YES, they always glam things and people up, to give the illusion and the dream to a world that always exists in our minds (cf: Mario Testino on CNN revealed)... it's VOGUE
