He described the show as built on "ideas of the prime and the perverse" — referencing 1940s housecoats, using lingerie as outerwear and creating a new silhouette that blended the 1940s with the 1970s.

"I loved it being so English, being about washing machines and clothes pegs and everything like that," top hatmaker Stephen Jones said. "British. Domestic."

"It was great," she said. "It was glittery romantic, but at the same time it had drama and sophistication and not too sweet, sweet, sweet. You know, it has a little bit of a punch. And sexy, sexy."

While many designers are showing more and more skin, Erdem opted for a subtle celebration of feminine beauty. There were some sheer and lacy outfits, but most were more modest, with either high necklines or sweetheart ones.

Wickstead set off her signature ultra-high waisted trousers with a white quilted mini-dress, a floral playsuit and oversized white hats. Several looks were asymmetrical and the entire show had a dreamy, fantasy feel.

"It was all about the bows and the ties and just kind of a happy, elated feeling," Wickstead said backstage after the show. "I like to keep things very pretty. That's what I love to do. The trousers were quintessential high-waisted, they were loose. It felt you could dance, you could play, you could have a great time. That's my modern woman."

He described the show as built on "ideas of the prime and the perverse" — referencing 1940s housecoats, using lingerie as outerwear and creating a new silhouette that blended the 1940s with the 1970s.

The outfits used strong colors — reds, pinks and yellows, among other hues — and showed off whimsical touches, including ones that seemed to be held together by metallic clothes pins.

The celebrity filled audience loved it.

With song classics "Stormy Monday" and "My Funny Valentine" playing in the background, the Erdem fashion house displayed glamorous, full-length evening gowns with long jeweled gloves and sparkly accessories.

Many outfits had floral themes and remarkable detailing, adding to the show's exuberance and opulence. Some even had feathers carefully attached. The palette embraced bold greens, pale pinks and yellow, strongly using colors throughout. There was no hiding behind solid black for Erdem.

While many designers are showing more and more skin, Erdem opted for a subtle celebration of feminine beauty. There were some sheer and lacy outfits, but most were more modest, with either high necklines or sweetheart ones.

The effect was entrancing. Nostalgia was in the air — the program featured a photograph of Queen Elizabeth II meeting Duke Ellington in 1958 — and the dramatic presentation artfully evoked the Big Band era.

EMILIA WICKSTEAD WANTS WOMEN TO HAVE FUN

Emilia Wickstead's show was high on romance and freedom, a celebration of femininity and possibility.

It opened with beautiful black-and-white ensembles with white tops that were almost completely sheer. Later outfits included elegantly draped, almost classical gowns that evoked ancient Greece.
