I think Zhou Xun's aged better than most actresses. When I see her with ZZY, I think of them as similar age or even ZX as the younger one, although ZZY is younger in real life. Zhao Wei's aged pretty badly though...pity. I don't think Zhou Xun is that attractive physically compared to her acting abilities, but I'm slightly biased since we are reportedly the same height and weight
Hey resident:alien that pic is AWFUL...thank God it wasn't posed, but if she looks like that without any makeup/touching up, then I don't think I'd look twice at her on the street.
Generally the ones that would be considered by males to be "hot/sexy" have posed in...err...revealing clothing. Like Chen Zihan, Alyssa Chia kind of but she's more cute...oh yes, Shu Qi that no one likes! Shu Qi is meant to have a hot image, not that I'll comment positively on it.
I think of GYY more as natural beauty than elegant. SFF is definitely more elegant. As for Eva, I'd say none of the above, but she looks more attractive in recent, touched-up pics so I might reconsider.
Someone mentioned what Vicki's been wearing to awards ceremonies - no offense, but you could dress a little nicer to an award than jeans. The dress she wore for MTV awards was nice though...the best she's looked in a long time.
