Vault 139 is a popular cruise club in West London with a different dress code (naked, underwear, full clothes, or any of the above) depending on the day - check their website for details. It isn’t particularly big or fancy, but it usually has a good crowd, and it’s one of the few cruise clubs in London that allows regular street clothes. Entry fee is £10, including coat check, a free drink, and re-entry. They have free entry days for under 25s on Sundays and Wednesdays, and for students on Tuesdays.
