>> Was there image processing to distill the dress into major components, hand tagging of variables (like short/long, color, etc), or just raw pixel data processed?
Its pretty clear that this is PCA on raw pixels of the images, so no, there is no hand-tagging or anything else. The eigendresses are just the eigenvectors from PCA projected back into the original, image-scale, basis.
