Give your loved one (can be partner, friend, bestie, family, etc) your sweater and say it looks better on them than it does you. OR force them to give you theirs and force them to say it looks better on you than it does them. (Conan Gray reference for Heather Day :3)
You: "hey bro" *cutely gives sweater*
Bro: "WHAT."
You: "it looks so much better on you than it does me :)"
Bro: "why did you do this?"
You: "it's December 3rd silly!"
Bro: "wtf"
OR
You: *forcibly takes their sweater* "Thanks bro"
Bro: give it ba--"
You: *hypnotizes them*
Bro: "it looks so much better on you than it does me...😵 💫"
You: "OMG STAWWWPPP >///<"
(Yeah uh... you might want to do this to a conan gray fan specifically lol)

Like in Dorian Gray's song Heather, on the 3rd of december you give someone a sweather you have a close bond with or love/like them.

Also known as "Heather Day," this is when you give your partner or romantic interest your sweater. For a crush it's like a confession, but for a partner it shows that you value them above all else. It also represents just how wonderful they are and that you feel your life has been made better by them. They are "your Heather."
Based on the song "Heather" by Conan Gray on his album Kid Krow.
