Hi MSC.
sounds cool. There were very occasionally a few more traditionally "Gothic" ensembles seen on DS. I'm thinking of some of Lady Kitty Soames' couture, Magda's mourning veil (Grayson looked truly fabou in it), Count Petofi's fur trimmed coat, Eve's black evening gown, a long black lounging thing worn by Cassandra in 1968... some of the 1840s outfits?
But, by and large, as you say, the screen explodes with color in DS fashion. And sometimes, as in Maggie Evans' patchwork skirt or some of Julia's more "aggressively" patterned suits, the explosions leave the ladies rather the worse for wear.
cheers, G.
