Hi Ashley. Welcome to MuT!!
when I think porcelaine doll skin...I think MAC Studio Fix. It´s a powder foundation and you apply it either with the sponge that comes with it, or with a powder brush (I prefer the later). it totally evens out your skin tone without adding too much color.
because of this, you´ll still have to wear blush and eye makeup, define your brows and wear something on your lips, otherwhise I personally look "dead" in it because my skintone is so even that it looks almost a little fake to me (in a good way though *lol*)
