1) Halloween is also very exciting because you get to see people dressed in funny or scary costumes as skeletons, vampires or ghosts. Some of them even have frightening masks or fake bloody make-up on.

2) I would like to invite you to my Halloween Costume Party. Everyone will
be expected to come in a suitable costume, the scarier the better! I'm sure
we will have a great time! It will take place from XX to XX pm, on Oct XX,
in my flat/ Club House/XX (place).
