Just like the Prince of Wales, the British public is being kept in the dark about Camilla Parker Bowles' wedding outfit.
The trio of designers kept their creations secret
Three designers - for her outfit, hat and shoes - remained discreet about their creations when they posed for the press three days before the wedding.
However, milliner Phillip Treacy said people will be surprised by how "fabulous" the bride will look.
Meanwhile Mrs Parker Bowles has been placed in a "best-dressed" list.
Her outfit has been created by London-based couturier Anna Valentine - but she gave no details about the colour, fabric or design on Wednesday.
She did say that it would have the detailing that was characteristic of her Robinson Valentine label.
"It's very elegant. It definitely suits Mrs Parker Bowles and she feels relaxed in it," she said.
Camilla Parker Bowles' style has won compliments
She added: "It's been kept a secret from the Prince, absolutely."
Milliner Philip Treacy, who had 10 hat fittings with Mrs Parker Bowles, said: "She will look fabulous. I think people will be surprised."
He said it was "a great honour" to create the hat.
"Weddings are usually difficult, but this one has been easy.
"The whole purpose, whether it's Mrs Parker Bowles or a housewife from anywhere, is that everybody wants to look their best."
Shoe designer Linda Bennett took practical considerations into account for the wedding shoes.
"They're very elegant but had to be comfortable at the same time because Mrs Parker Bowles is going to be walking around a lot on the day."
Mrs Parker Bowles was very involved with the design - "They're very simple and feminine and quite a signature look of ours."
The style bible Harpers & Queen included Mrs Parker Bowles best in its "showstoppers" category of women, as well as Kylie Minogue, Naomi Campbell and Kate Winslet.
The judges said she could look "demure and sexy" when dressed up for an evening event.
"These women deserve their awards for knowing just how much decolletage to flash (never too much) and just how much leg to show (just enough)," the magazine said.
"They show a keen eye for colour and texture and manage to achieve that most magical of combinations - looking demure and sexy at the same time."
