for t-shirt i would say buzz rickson. that thing build like a freaking tank. i got mine for almost 4 years and the collar still the same as the 1st day i bought it. i also like Studio D' Artisan t-shirt for the same reason.

as for denim and stuff i would say most of my favorite range from samurai, iron heart, pure blue japan, to nudie and naked and famous. our local brand like cheese denim also quite nice.

for formal attire, i like dockers but its not durable as last time. i still bought it from time to time thou.
