Among the young and beautiful are an equal number of middle-aged clubbers. One woman in suspenders even introduces us to her parents.
Catching up with Hannah, we learn she runs fetish night Club Subversion, and organises the annual Rubber Ball. But Pimp And Fluffy caters for those who just like to dress slightly dangerously. "A lot of people want to dress up," she says. "You become someone else for the evening. It's escapism at its best."
We head to the Fluffy Room to hear house legend Alex P. The crowd dancing to his electrohouse are infectiously bouncy, and we're carried away in the fun.
The mix of house, breakbeat and funk satisfies everyone. Dancing clubbers are whooping, grinding against the pillars or climbing on the seats in their music frenzy.
A long journey means we have to leave with a heavy heart at 3am, but we promise to be back. Maybe next time I'll even have graduated from pimp academy.
The next Pimp And Fluffy evening is 22 December; Hidden, 100 Tinworth Street, SE11. pimpandfluffy.com
