I'm sorry, but I'm a bit of a purist when it comes to vintage. I'll be the first to say "chop the hem, raise the skirt" IF something had damage down there, and the only way to return it to wearable condition was to repair it. That's just peachy keen with me.
But this gal from Elle magazine has gone too far. She's whacked the bottom off a freakin' DIOR gown, and to add insult, has paired it with a tank top (A TANK TOP!!!!) to make a "dress to wear to a wedding". Now, she does warn against pairing such fine items with such a lowly fabric as cotton. No, she has used a silk and cashmere tank. Well, ok then. As long as you didn't pair it with cotton.
