Snowpiercer Alexandra Cavill (Played By Rowan Blanchard) Screen Worn Jumpsuit & Short Sleeve Shirt Ep 210

This wardrobe set belonged to Alex Cavill, as played by Rowan Blanchard, and was worn in episode 210, when she pretends to pledge her loyalty to Wilford in order to distract him while Bennett and Javi turn the train to head towards Melanie. Wilford senses the shift and has Alex call up to the engine, but she lies and says its just an avalanche. LJ calls her out, which infuriates Wilford.
