If possible, yung cheap. Haha. And yung hindi masyado hapit. Kumbaga straight cut lang pero maganda pa din yung fit. Basically, for work. Haha.
If you're very particular with what you wear, go to a tailor. It's the best way to have what you exactly want.
For brands, it still depends on your budget and fit. Different strokes for different folks. I recently noticed that Freego has a good line of chinos. Also DKNY has good fit. But that's for me. Your body built, leg built, leg lenght and fabric are only a few things to consider.
Libre naman magsukat sa mall eh. hahha
