For the suit of her Earth Two equivalent, see Killer Frost suit

The Killer Frost suit is a protective suit formerly worn by Caitlin Snow of Earth One as Killer Frost.


Caitlin wears a protective suit as her evil alter-ego, Killer Frost, shortly after she was recruited by Savitar.[1]

The suit was first seen in a possible future, through Cisco Ramon's vibe, where Caitlin, having become known as Killer Frost, took on Vibe.[2]

This suit is similar to the suit worn by the Caitlin Snow of Earth Two, in terms of the design and the colors.

The suit includes a long dark blue coat with silver details, which reaches down to a little bit below knee length. The coat is zipped up to form a corset-like top with a snowflake-like symbol in the middle of her waist, possibly featured as an 'emblem' for the suit. It also has a dark blue dress underneath the coat and long dark blue boots that go up to her thighs.

Caitlin eventually merged with her Killer Frost side and abandoned her alter ego and her suit.
