i think grayson was perhaps what was once described as being a "handsome" woman and i find her to be quite striking.
after they discarded the ghastly wig from the "miss hoffman" period i think that they actually made julia look quite chic.the cropped,copper colored hair,the false eyelashes,the gloves,the suits,the jewelry.i'd say the show's costumers attempted to make julia look competent and sophisticated.
it's only with today's eyes,when middle aged women run around dressed like teenagers,that she can come across as "dowdy".
