Halloween costume ideas

This year I am planning to go to one or even two Halloween costume parties. What I will dress up is still the problem since most of my costumes are booked by others. I had the following ideas for what I could wear based on what it looks like will be left and which is not an animal costume, superhero/villain or Star Wars character:

1. Ninja uniform with spiked skull mask, the spiked skull mask also has a bit of a neck and shoulder part.

2. Schoolgirl uniform with the same mask as mentioned above, the problem is that my arms would then be open which breaks the effect a bit.

3. Red devil costume with demon mask where only parts of my lower jaw shows. I can use facepaint for that section.

4. Large purple medieval dress with padding around the chest with female mask and wig.

5. Red/gold medieval dress with mask and blonde wig plus padding. More different mask face options for this costume due to being a different character. I could try and go for a freaky cute look.

6. Nun costume with padding, mask and long white gloves, the costume is a bit short for me.

7. French Maid with padding, mask and wig plus long white gloves. I have worn this before for a Halloween party which turned out to be fun.

8. Indian, either male or female costume with wig.

9. Venom, this is actually a superhero/villain, but I might wear this if I go with people I know to an event.
