Basic Body Parts
Fairies have two major body parts. One would be the human like body, which is generally similar to a human’s figure. The second would be the wings. In some cases, artists add a little twist with their fairies. They do this by giving them pointed ears. Some would even make the head shape a little pointed too. It still depends on you whichever style you want to go for.
So basically, you would just have to draw a woman. Then, make her whimsical by adding a pair of wigs on her back. For the hair, you could either give her extremely long hair or extremely short hair with a pointed head. The hair color could also vary depending on your imagination. Almond shaped eyes are common among fairies too.
Clothing And Accessories
For clothing, your fairy can wear something that is close to nature, especially if the type of fairy that you want to draw is the kind that lives in the forest. Most fairies appear to be wearing a miniskirt that has asymmetrical edges. Their long slender legs are also prominent with their clothing. For accessories, you can draw a flower garland around their head of around their waist in a way that it would look like a belt hanging loosely. You can also add a pouch to their belt, just like the one where Tinkerbell keeps her fairy dust.
For your fairy to appear more magical you should draw her in her environment. Again, this would depend on you. She can be playing in a pond, beside a flower or sitting at a rock. Whatever the environment is, make it appear magical and out of this world.
