[monologue]

Going only by what I observe in Bangkok, I see that rap culture and fashion is big among young city people, but I think that on the whole Thai people are still very conservative with regards to fashion.
Those with money go for big conservative European boutiques, those with less go for a more grungy look but they still have their limits to how grungy they want to appear. It's more of a conservative, ''pretty'' grungy look.
In a nutshell, I think Thai people are quite conservative in their fashion, even when they try to be ''different''.
That's just an observation - I'm certainly no fashion guru for sure. Good luck with ur project.
