CarolineRose - That's funny, I just bought that very trench yesterday! I love it. I keep saying it's the closest I'll ever get to Burberry Prorsum Spring 2010 (posted about it in the Zara thread). It's a yay for me!
hyunkyounglee - If I had to choose one, I'd go with the Wang dress - it's iconic. A lot of my Phillip Lim pieces I buy at the end-of-season sales and I would personally wait on the sequin dress...unless you're planning on wearing it within the next few months. It's pretty, but I'm not sure it's $900 pretty.
