y leh???
I dunno what you meant.
You can wear tight clothes if you want to wear them.
What do you think is going to happen that might prevent you from
wearing tight clothes?
I don't think we have a fashion police in Singapore and neither
does the law states that Men are not allowed to wear tight
clothes.
If you're not breaking the law, then I don't see your worries
here.
Maybe you are restricting yourself from doing so?
