It's so cold outside that girls’ shirts become see-through and their nipples pop out like they're showing off.

My friend’s shirt turned into a see-through window, and everyone in the mall was staring at her.

My neighbor’s kid walked outside and came back like she had a tiny snowstorm on her chest.

My cousin’s shirt was so thin, I could see her nipples like she was wearing a winter magic shirt.
