What do real Fairies look like?
Fairies can look like humans when in fairy form, only they have wings which can be different shapes, sizes and colours, some fairies have different coloured skin like blue, green or purple, sometimes their skin may be sparkly (especially if they have unusual coloured skin). They can have any eye and hair colour at all, no matter what their age. Sometimes they can go into human form or put on their “glamour” like the above states, and look like a human, although when this happens they loose some of their powers for that time, and they do not have their wings, also they are immune to things like iron, which otherwise in fairy form – would harm them.
You may not like this answer but I am serious. There are many imaginary things that can make exciting and enjoyable fiction stories. Many people enjoy them and so do I. Just remember, these are NOT REAL: Fairies, dragons, time traveling, Cupid, reincarnation, werewolves, genies, zombies, telepathy, mermaids, vampires, lucky numbers, tooth fairies, homeopathic healing, magic (of any color), leprechauns, spontaneous human combustion, astrological influences, Vulcan death grip, clairvoyants, astral traveling, Superman, angels, charmed or lucky objects, unicorns, hexes, space aliens on Earth, light sabers, paranormal anything, dead people walking around, fountain of youth, telekinesis, spirit guides… or supernatural events of any kind. .
