Should I wear make-up on my eyebrows before a transplant? I'm having a brow transplant to redefine/reshape my brows

I don't like my eyebrow density, shape, & angle. The existing brow will be filled to create denser coverage & completely redesigned. I've a specific look in mind & wonder if showing up at the clinic with eyebrow pencil on would be a good idea, as I don't want the surgeon to misinterpret me? Would it be better if I brought along drawings/photos of similar looks to what I desire? Its such an exact procedure & a few hairs out of place would ruin the look. Being a model exact standards are required!
