Does anyone knows of a place with free mirror like in pasir ris or smth but not at scape that we can use for free like a venue for meeting.?

I find scape to be one of the places that have been set up for dancers (especially street styles) to practice for free. In fact, they have increased the mirrors there over time! As a dancer myself, that's one of my favourite places to practice.

Otherwise, you could check out the polytechnics. They might chase out folks who are not students though!

I don;t know about free, but you can check if any secondary school is willing to open up their studios after school hours or during weekends.

I remember we rented a studio from my secondary school for about 5 bucks per person, and we only had 6 people. WE were there for about 2-3 hours.

Then again, this happened some 10 years ago, so I can't be entirely sure of the numbers
