Bruce Oldfield praises Sarah Burton's royal wedding gown

(CBS) Bruce Oldfield may have not won the assignment of designing Kate Middleton's wedding gown, but he's still a fan of what the new British royal wore down the aisle last Friday.

"Beautiful dress, well done Sarah," the London-based designer tweeted, giving props to Alexander McQueen creative director Sarah Burton, who designed Middleton's now-famous lace and satin gown.

Oldfield, who often dressed Princess Diana, was considered a top contender to design Middleton's much-anticipated gown. Rumors first circulated in January when Middleton's sister Pippa and mother Carole were spotted at Oldfield's London boutique.

But just two days before the royal wedding, the 60-year-old confessed to Women's Wear Daily that he was not commissioned to be the dressmaker.

"It has been such a subject of rumor and speculation over the past months, but I am not designing it," Oldfield said.

Oldfield's gowns befit a formal occasion like a royal wedding. His style is strictly traditional and timeless, with gowns made in classic bridal fabrics like crushed velvet and taffeta.

His celebrity clients include Samantha Cameron, wife of the British prime minister; Queen Rania of Jordan, model Jerry Hall; singer Barbara Streisand and Welsh actress Catherine Zeta-Jones.

Oldfield, from northwest England, graduated from Central St. Martins (the same fashion college the late Alexander McQueen attended) in 1973. He started his ready-to-wear collection in 1975 and his couture label in 1978.
