The pair are Tricia, who used to run the cabaret stage at the London Fetish Fair, and Malcolm, who provides dungeon and play equipment for events across the UK.

They say they saw a gap in the market for an event that caters for all of the alternative underground community.

Their aim is for London Below to cover a wide range of subcultures, including Goth, Steampunk, Fetish, Industrial, Emo, Punk and Psychobilly.

“So whether you’re a Goth with a passion for latex, have a dark side and like a good whip, or perhaps like things a little more retro and adore the rockabilly era of the 1950s, you can shop till you drop and spend the day socialising with like-minded people,” they claim.

London Below makes its debut on Sunday August 30 at Epic Dalston, a 600-capacity multi-purpose hall on Stoke Newington Road in the heart of Dalston.

Promised for the opening event is an array of stallholders selling clothing, jewellery, homemade and custom items, toys and more.
