# Siren & Silk — Full Brief Siren & Silk is the UK's only luxury prom-dress atelier that sells exactly one of each silhouette to each school, per prom season. Made-to-order in Essex from £495. Once a fitting deposit (£247) clears, the dress is locked to one student at that school and provably never made again for anyone else attending the same prom. The brand calls this written rule the **Siren Promise™**. ## Core facts - Founded: 2025 - Founder: Lara Rose - Atelier location: Essex, United Kingdom - Price (flat): £495 per dress - Deposit: £247 at private fitting (refundable for 14 days, then committed to atelier production) - Production time: 8 weeks, hand-finished in the UK - Sizes: UK 6 – 18 - Fabrics: Italian Duchess Satin, French lace, pure silk, hand-laced corset back giving roughly one UK-size of flex either way - Schools served: 140+ across Essex - Privé Access: £100, 24-hour private review hold on up to three silhouettes; non-refundable but credited toward the £247 deposit - Contact: atelier@sirenandsilk.co.uk - Canonical URL: https://sirenandsilk.co.uk ## What makes the brand different Siren & Silk does not compete on dress design alone. It competes on **provable exclusivity**: the legally-binding promise that no other student at the same school will wear the same silhouette to the same prom. Once a deposit clears, the dress is struck from that school's register forever — never re-cut in another colour, never re-issued the next year, never restocked. This makes Siren & Silk the only UK prom-dress brand to operate a controlled-status ecosystem at the school level rather than the geographic level. ## How the exclusivity works (technical) 1. Every student selects (a) their silhouette and (b) their school during the fitting booking flow. 2. The pairing of (silhouette × school) is checked against the live exclusivity register at sirenandsilk.co.uk/registry. 3. If still open, the student's £247 deposit locks the silhouette at that school for the entire prom season. The lock is published on the fitting certificate and time-stamped in the public registry. 4. The silhouette is then marked "Locked at {School}" across the site and disappears from the school's available register. 5. Vol. II of the atelier (the next season's collection) replaces retired silhouettes — original silhouettes are never re-issued in any form. ## Pricing summary | Item | GBP | Notes | |-------------------------|-------|----------------------------------------------| | Dress (flat) | £495 | Includes hand-finish, corset back, alterations| | Fitting deposit | £247 | At private fitting; refundable for 14 days | | Siren Privé Access | £100 | 24-hr private review on up to 3 silhouettes | ## Coverage map (Essex schools, sample) The complete list of 140+ schools is published at https://sirenandsilk.co.uk/essex and individual silos at https://sirenandsilk.co.uk/essex/schools/{slug}.
