Snooki, Lady Gaga, the Situation & Avatar
If you're looking for a more outrageous and eye popping choice you may lean towards Lady Gaga, from her meat dress, to blood spewing performances she will likely be imitated from her bow hair style to those hard to mimic costumes that can be order off her web site for $50 US + shipping, some are willing to pay to look the part.
From the widely popular movie of Avatar some pay take the artistic approach to alter their image to reflect the blue, creepy creatures that graced the big screen in this hit movie.
For those guys that want to get in touch with their manlier and masculine side will mostly be the Situation for Halloween-another star of the hit MTV show Jersey Shore. With spiky hair, sunglasses, wife beater and jeans all seems like a cost saving costume- less you don't have the 8 pack that he has... then you may need to pop into a costume store in order to purchase the plastic version to complete the look.
Whatever costume you choose, enjoy the day this is the one day of the year you are allowed to take on the persona of another person and can enjoy every minute of it!
Happy Halloween!
