It also depends on her skin type. my ex never got a sun tan no matter what she did. She could stay naked in bright day light for half a day or longer and would turn red like a lobster but never brown. And over night her skin tone will have vanished back to white as porcelain. No color from sun beams ever stayed on her longer than a day, and as i said, the only color she would ever catch is some reddish shade of pink and not the typical tan brown.Damn, she hasn't been there long, still lilly white!!!! Would look good against a dark skin!!!!
