(lego custom minifig crew of the bettys kiss by dunechaser)

Making up WWII pilots as custom minifigs is pretty easy, you get a Lego life vest, the leather jacket minifig torso, light brown legs (like the ones on the german solider from the Lego indiana Jones theme), either black, brown or yellow minifig hands, flying cap and officers cap, both in brown, and you’ve got the basic WWI fighter pilot look, this means that the only real thing that allows you to make this kind of minifig custom is the minifigs head, and heres where you can really go wild, whilst in this case each minifig head is unique, they are standard pieces, but there’s nothing stopping you from making more unique ones with custom decals.
