Hello there. We would be able tgo make a replica of either of these gowns. The Ambrose or Silvia would be the mos accurate, as we have been able to find detailed photos of the front and back of those two gowns.
Delia would be made with lace and silk charmeuse. Ambrose is ivory lace over tulle. Silvia would be french chantily lace.
Delia/Ambrose have a little less detailing on the dress, so they would be less expensive - $599. The Silvia style would be $699 - those prices are including shipping.
Generally, it takes about 6 weeks to make and ship the dress from the time that payment is recieved. We say 6-8 weeks to be safe:)
