The Sinner Circle Masquerade Party Night 2026

Utrecht's Secret Masquerade Party Night falls on Saturday 31 October 2026, 20:00 to 02:00, at a location in central Utrecht that is announced only to ticket holders shortly before the night. Halloween on a Saturday, with masks already built into the concept — the calendar did The Sinner Circle a favour here.

The night is for open-minded women and couples, and it is deliberately pitched as the accessible option: the organisers built it for people who are curious and open-minded but find walking into a parenclub too big a step. So the shape of the evening is a proper party — dance floor, music, meeting people, drinks and bites, a welcome drink on arrival, DJ Diamondskull on the decks — with a small, simple darkroom on site for anyone who wants to slip away discreetly. The organisers say plainly that the darkroom is a basic extra rather than the main event, and that the focus stays on the dance floor.

The dress code is casual-to-sexy chic rather than fetish: look stylish and sexy, smart trainers are fine, sportswear and hoodies are not, and the mask is not optional — you can buy one at the door if you arrive without. Entry is 18+ and valid ID is required; without it there is no entry and no refund. Couple tickets must be used by an actual couple, male-female or female-female, and there is no single-man ticket at all. Photography and video are only allowed with prior permission.

Tickets come in four types through the organiser's own shop. Early-bird places for a woman or per person in a couple were advertised at around €33.39 when this page was written, rising to about €35.39 — with the couple tiers priced per person and sold in twos, so a couple should budget roughly €67 to €71, and the ticket provider may add its own service fee at checkout. Treat all of that as an indication and let the shop confirm the exact amount.

DJ Diamondskull. A welcome drink is included on arrival.
