Both Misty Day (Lily Rabe) and Zoe Benson (Taissa Farmiga) had spectacular outfits in AHS: Coven. Most of the best ones are on that site, though not all of them.
In fact, all the outfits for all the characters were great but those two castmembers particularly stood out. You can really have a lot of fun with witches and the costume designers this season outdid themselves. This outfit of Farmigaโs was one of my favorites. If I had that, and looked good in it as she does, Iโd wear it even in summer.

Costume design is really an undervalued language of its own, and tells its own stories; the costume designers in this show were so good that if Iโd just seen any one of the character outfits laid out on the floor I couldโve told easily which character they belonged to, even if theyโd never worn them before.
Farmigaโs character as she embraces her witchhood gradually changes her dress from mainstream fashion to the above sort of raiments. Literally her story is told in her clothes, piece by piece. Thatโs skill, right there.
