Temperley, a favourite of Kate and Pippa Middleton, said she wanted to update the '50s couture look and make it accessible.
The designer said the conical hats the models wore exemplified the classic couture feel of the spring collection, which was set in a grand chandeliered hall.
"I wanted to create something modern and sleek, something that gives the feeling of the dream of couture," she said of the hats, which were similar to the style that Audrey Hepburn wore in "Breakfast at Tiffany's."
Working from a soft palette dominated by powder blue and ivory, Temperley showed off flirty, tea-length circle skirts and dresses that accentuated a tiny waist. A theme was skirts with semi-sheer horizontal organza stripes, which Temperley said was to show a bit of leg and make the retro look more fun.
Textures were luxurious and soft with lace, silk, brocade and tulle with flower appliques.
Temperley is best known for her romantic evening and bridal gowns, and is launching a more affordable line at British department store John Lewis.
On Friday, Kate Middleton, now known as the Duchess of Cambridge, wore a Temperley ice blue dress with white lace sleeves to a tea party in Malaysia.
