Ranking The 20 Best Arrowverse Costumes

After spending the majority of The Flash's third season engaged in a mental battle with Caitlin Snow over the use of her own body, Killer Frost eventually took complete control towards its conclusion. Freed at last with no intention of relinquishing control, one of her very first decisions was to get herself an outfit.

With a low neckline, long sleeves and bejewelled lapels, our Killer Frost certainly looked at home wearing this corset-like jacket. It was similar to Black Siren's outfit in that it managed to be fashionable yet intimidating at the same time, portraying the character like the femme fatale that she was.

It's a shame that once Frost and Caitlin began coexisting, the ice queen exchanged the outfit for a blue leather jacket and jeans. While she certainly pulls this (and the newer Season 5 look) off just as well, the Season 3 outfit made much more of a statement and presented her like the force to be reckoned with that she truly is.
