As a costume designer I love Scully’s S9 descent because it is literally a descent. On the most practical level she’s not dressing strictly professional anymore, so we get more street clothes (ie: cool leather jackets.) She’s also emotionally so done and so closed off. Hence the turtlenecks and dark colors (sooo much gray, black, burgundy.) Her wardrobe strikes me as utilitarian and armor-like. She’s not having fun. She’s not here to flirt. The love of her life is God knows where and even knowing where won’t help either of them so she’s here raising their son just in case it’s the last link she has to Mulder for the two of them. Her clothing is here to do two things: protect and get the job done. She looks badass but also so tired of it all. She was never one to express herself through her clothing before, but we got hints and whiffs of sexuality with the silky professional button downs unbuttoned j u s t lower than office appropriate while running around bagging and tagging aliens with Mulder, and her suits which were professional but also fucking hot. Now its turtlenecks all the way down and leather trenches, and it’s like my girl is not here to play she’s here to SLAY and she means mostly the kind when folks end up dead. Girl is ready to cut a bitch in those clothes.
