Oscar's technical branches are more similar to the acting branch than most people realize. The costuming branch is no exception. They have their pets who can't thread a needle without getting nominated, and other designers who they strangely ignore repeatedly despite fine work. And like Oscar's acting branch they have "hooks" that they fall for with great regularity. Certain time periods are baitier than others and so forth. Iconic gowns help but are no guarantor. And like the acting branch, they tend to prefer realism and authenticity to leaps of imagination and genre stylization. Most of the time anyway... they don't have quite as many genre prejudices.
