Most women I've known are borderline unattractive (aesthetically) without makeup. Portman comes close to natural beauty - a rarity - but it is only evident when she is visibly happy. Disposition helps a lot.
If you're a guy and merely want to sleep around, makeup is fine. But if you want to wake up to the same person each morning, she better be attractive to you for reasons other than having smooth skin and a tight body (e.g. intelligent, good conversationalist, great disposition, sharp sense of humor, etc.).
