What is Siren & Silk?

Siren & Silk is the UK's only luxury prom-dress atelier that sells exactly one of each silhouette to each school, per prom season. Hand-finished in Essex over 8 weeks from £495, the dress retires from a school's register the moment a £247 fitting deposit clears — never re-cut for anyone else attending the same prom.

How does Siren & Silk's school exclusivity work?

Each silhouette is locked to one student per school for the entire prom season. Once a £247 fitting deposit clears, the dress is struck from that school's register and provably never re-cut for any other student attending the same prom.

How much does a Siren & Silk prom dress cost?

£495 flat per dress. A £247 deposit is paid at the private fitting (refundable for 14 days, then committed to atelier production); the balance is due on completion.

Where are the dresses made?

Hand-finished in the brand's Essex atelier over 8 weeks using Italian Duchess Satin, French lace and a hand-laced corset back. Made to order in UK sizes 6 – 18.

What is Siren Privé Access?

A £100 24-hour private review hold on up to three silhouettes. The fee is non-refundable but credited toward the £247 fitting deposit if the student proceeds.

House Rule · 01

When she claims it,
it disappears.

The minute her name lands on the certificate, the dress slips off her school's register. No remake. No "same gown, different colour". No surprise twin on the dance floor. We've held this rule since day one and we're a little smug about it.

Cut, draped, and laced by hand — in Essex

The only her in the room

Lock the silhouette to her name and her school. We don't recut it for her friend's hallway, her cousin's prom, or anyone else's photograph. One girl. One gown. One unforgettable arrival.

Made for the camera

Italian Duchess Satin, French lace, a hand-laced corset back that flexes a full size either way. Eight weeks in our Essex atelier. She'll photograph like couture and dance like she's borrowed nothing.

Beautifully simple, mum

£247 at her fitting, refundable for 14 days. £495 all in. No subscriptions, no payment plans, no nasty surprises. One bill, one bespoke gown, one beautiful night.
