go big or go home!
Decorate with your favorite color pallet.
Rent out a restaurant or/and Venue.
Invite only your close friends and close family (co.vid).
Get a DJ (or make a playlist on Spotify or something)
Wear a stunning dress.
Make a dressing assignment (formal, casual, etc)
I feel like that is all but ofc you could add anything else you wanted.
