Prime Minister's wife Samantha Cameron, in her role as Ambassador to the British Fashion Council, was at the Evening Times backed Scottish Fashion Awards to present the top award, Scottish Fashion Designer of the Year, to Jonathan Saunders for the second time.
Stars at the Glasgow Science Centre event included Lulu and Dame Shirley Bassey, who wore a tartan dress and held a sporran-shaped handbag.
Winners included Tali Lennox, daughter of pop singer Annie, who scooped Scottish Model of the Year, and Skins actress Freya Mavor who was named Scottish Fashion Icon.
Mrs Cameron, in a lime green dress by Scottish designer Christopher Kane, said: "I'm thrilled to be here - these awards celebrate the very best in Scottish fashion and remind us that Scotland is home to not only inspirational designers but also a very important textile industry."
Other leading lights of the fashion world included male super- model David Gandy, Scottish actress Louise Linton and New York-based celebrity stylist Derek Warburton.
Henry Holland was named International Designer of the Year and photographer Rankin took the Hall of Fame 2011 award.
Harris Tweed Hebrides won Scottish Textile Brand of the Year while Scottish Young Designer of the Year went to Henrietta Ludgate and Scottish Accessory Designer of the Year to Bebaroque.
The awards event, now its sixth year, was followed by a dinner and chart star Yasmin performed at the after-show party.
Tessa Hartmann, founder and producer of the event, said it was "an impressive showcase of Scottish fashion talent" and that it would "encourage retail growth, investment in our manufacturers and highlight our creativity globally."
