Raf never seems to create... clothes. And by clothes, I mean garments that flatter or at least respect the shape of the body. He has a vague idea of what clothes are, and this shows in the modes in which he can "design": supremely pedestrian or conventional silhouettes (offset by some unique color or print), obvious attempts at "fashion" (hipbone cutouts), or something just plain unaccountable to the wearer. Instead of having the mind of a designer, I believe Raf really has the mind of an artist. In the video, the "clothes" look stiff, unforgiving, impervious to motion. They appear as if they should exist on a flat plane instead of on a living, breathing human being (and, yes, his work for Dior always looks better in photographs than in real life). This leads me to suspect that Raf designs in two dimensions rather than in three. The body is treated like a smooth canvas. Those skirt-shorts, for instance, look like they're fabric stuck between the models' legs instead. In addition, his perceived strengths as a designer (his sense of color, texture, and print) just serve to reinforce what I've always thought of his work. Maybe it would be better if he changed his chosen medium of expression.
Personally, I abhor words on clothing. They always seem like lazy shorthand when you're having difficulty getting your message across in your designs.
