The woven sleeves look like the sleeves for the outfits Kathy's and Charmaine's ZZRs wore, though in a different color. I actually prefer her blue-and-white outfit. Nonetheless I like the last shot of Liu Jing as well! She looks pretty in a cold and sharp way.
Here are some even more beautiful pics of ZZR in a romantic moment with ZWJ. The scenery's gorgeous!
And pics of Zhu'er in a new look (after she returns from the "dead"). Seeing how cute and dainty Zhang Meng looks, it's very difficult to believe that Zhu-er's actually the oldest of the 4 ladies.
