Part of why I will neveeeeeeer get a tattoo. As others have said though, makeup. Get a liquid foundation that matches your skin, let it dry, powder or conceal it as needed. Shouldn't be too too hard as long as it isn't dark dark.
Cosplay 1: Sailor Venus (Commissioner failed to make 4 month deadline)
Update: August 10th.... still nothing.
Reality: Recycled or no cosplay at all. Got to love commissioning! Thanks everyone!! Serious thanks to Dulcinea, who actually made the deadline for the accessories far in advance and of outstanding quality. Sucks they won't be used.
