There are a lot of cheap great finds in the Market! Market! Fashion Market if you know where to look. There's NAVA (although they're kinda expensive for tiangge clothes now) and a few other nameless stores. I know that doesn't exactly sound helpful, but I'm just saying you should check out everything when you're there!
One of my recent finds is this chiffon top that only cost me P280. It's nothing crazy special but I have been looking for something like this for some time now, and I'm just happy that I got one for cheap.
Tiangge top / Maldita skirt / Pinkbox bangle and necklace / Ferretti shoes
And that's it! :D I just have to ask: where is your favorite tiangge and why?
