yes they did. singaporeans are generally terrible dressers. the ang
mohs in singapore are equally bad.
and yes, I admit I'm also a terrible dresser but even I will not
go to a casino or concert dressed like that 
Frankly I don't see the need to dress up to go casino, except
that the casino enforces it. Probably so that it would seem more
"high-class"
For concerts I guess it's respect for the performers. And on the
streets, I don't really care.
