Pink hair for the girl fairy! I like that!
I don't think of those type of female adult fairies as wearing socks or stockings - like the unusually coloured animals, I assume that these fairies have had the colour of their bare legs magically changed into different colours. Though this green and pink version is my least favourite one, and this particular fairy does look as if she is wearing her underclothes (a camisole) on the top half of her body. The others are great, however; I think that the boy works OK as a fairy. He could have got his shirt and belt from a neighbouring elf or dwarf, perhaps.
