Considering Weiss lives in Atlas, she's probably more used to the cold than the others.

She still needs a new outfit, but not because of the cold. Her current one is torn up, bears the Schnee emblem on its back, and makes her too conspicuous.

She should also consider cutting her hair short so as to make her less identifiable as the missing Schnee Former-Heiress.
