chung cheng high.
i came from a school with 7 metal buttons too. 
anyway dunno abt cool sch uniforms - MANY schools go for white
white or white blue, with little variations here and there. so
nothing much to compare. and students dont like to wear their
uniforms properly too (im equally guilty in the past).
mabbe instead should ask which school has the best (and most cock)
PE T-shirt design or colours.
for that i mus say meridien JC's rather nice! looks like those
jerseys you can buy at sports shops.
