The easiest possible style, that can wary from perfectly natural to more pail and deathly looking is the middle age, Marrie Antoinette style. The less violent goth style is easily developed from this one.
First off it takes powder, and lots of it. Use baby powder and a big brush and just brush it over your face and blend it in, middle age style was characterized by paleness, and their powders were made by grinding rose pettals. Baby powder will do.
For the eyeshadow, use something natural, like an earthy colour, or nude colours like baby pink, and the spectars of white-like colours, like dirty white, pure white, elephant tusk and such. Red is an option when applied lightly.
Eyeliner wasn't used back then but that doesnt mean it shouldnt be used now, in moderation. With brown hair a little brown eyeliner gently rubbed under the eye could look good.
The eyelashes should also be a neutral brown or black colour, but nice and long.
Eyebrows shouldn't be plucked, natural is natural...
as for the beauty spot, I find it overrated but it would probably look good on a renaissance fair or a themed night out.
the clothes should be again nude white and pink colours, but black, dark red or green combination looks exelent also.
Working in this same style but with liquid eyeliner and/or a sharper, deeper eyeshadow worked in the eyes can look very goth, but not in the sharp way, but in the Renaissance (duh!) old way.
