It’s called /shiver but it comes from Eureka so expect to part ways with millions of gil. Search the market board for: “Ballroom Etiquette: Insufficient Petticoats”.
It's not the same. /shiver just has you standing there freezing your arse off in a tucked position in an attempt to stay warm. A /warmhands emote would express that your hands are cold, and can be expressed many ways; OP was not specific. I would imagine a persistent emote that has your character blowing warm breath into cupped hands and then rubbing them together. In a sitting position your character can sit on their hands, or tuck them between their legs. There is also simply just putting your hands in your pockets, but that would look weird if your character isn't wearing something with pockets.
