Fairy costume dress & wings
A popular costume idea for a 12-year-old girl could be a character from a favorite movie or book, such as Hermione Granger from Harry Potter, Katniss Everdeen from The Hunger Games, or Moana from the Disney movie. Other options could include a classic costume like a witch, superhero, or unicorn.
A good costume is something like a devil or a vampire.
The Grand Heritage Elvis Costume would be a good costume for a 14 year old boy.

There is not a specific costume that is the best for an 8-year-old boy, the best thing to do is to explore his interests and then allow him to pick a costume of a character that is interesting to him.
A good gift for a 13-year old girl can be many things like make-up, clothing (fashionable jeans, T-shirts, dresses, underwear), cash money, real jewellry, costume jewellry, bank account, car and many more. The worst gift of all is giving a girl a voucher for plastic surgery.
