Themed parties. Always more hassle than they’re worth. (Come, now, it’s impossible to look glamorous while dressed as a tube station.)

Thankfully there is a less humiliating alternative. Unlisted London’s new Sparty service will bring a spa party to your home. Relax with up to 30 of your friends whilst a fleet of therapists arrives with fluffy slippers, bathrobes, flowers and hot towels to transform your humble abode into a holistic haven.

They provide the candles and the music. You provide the stressed-out candidates. Then, simply sit back and let the indulgence begin. Choose from a selection of mini-facials, foot rubs and massages, all performed by Unlisted’s famously good, well-mannered staff.

And you needn’t worry about smudging those freshly manicured nails; you won’t have to lift a finger, because Unlisted London can also lay on the canapes and the wine.

Best of all, you won’t spend the evening being asked: “And what are you supposed to be?”
