Will another girl at my school have the same prom dress?

No. Siren & Silk sells exactly one of each silhouette to each school per prom season. The moment your name is on the certificate, the dress is permanently locked to your hallway.

What sizes do you make?

Every silhouette is made to order in UK sizes 6 to 18. The hand-laced corset back gives roughly one size of flex either way for the perfect fit on the night.

How long does a prom dress take to make?

Our atelier lead time is eight weeks from confirmed order to delivery. We recommend reserving by January for a summer prom.

How much is the deposit?

A £275 deposit secures your school's lockout. The balance is settled at your private try-on, in cash or by card.
