Never heard of Uniqlo, will check it out though pati yung Topman na nababasa ko dito kanina.
As for my best shop, hmm never liked bench, specially their polo shirts ang lousy sa akin. It's either too tight or too big. They offer good and cheap denims though, okay pang araw araw if you don't want your Levi's to take that kind of beating.
Penshoppe I guess ain't my style.
RL, Lacoste and A/X is pretty good. Can't go wrong with these brands if you know what you're looking for, and madali dali din hanapin if you need to re-stock your stuff.
JCrew is good too, comfy clothes and casual. Di ko lang alam if meron store dito. So there's that.
