Sophie Dahl, 23, once famed for her plus size, was yesterday unveiled as the new face of Scottish knitwear brand Pringle -- with a stunning new slimline figure .

“My size had become a public fixation. This isn't a fat or thin issue. It’s just about looking the best I can by being healthy and toned,” she said in a promo press junket. But she added: “The best thing is I’m back into my size 12 Dolce and Gabbana dress. I feel good and look good. I’m the way I want to be.

A Pringle spokesman said: "She exudes British glamour from every pore." The 1950s-style "Miss Argyle" adverts will be released in March.

Sophie credits her new look to fitness guru David Marshall, inventor of "the banana diet" (I swear I didn't invent this).

Of course, this is Ana Beatriz Barros at the Valentino show in Paris. If you had done your homework on her VS ad earlier this week, you would have recognised her immediately! Need another chance? I have just scanned another stunning VS ad from Vanity Fair, here you go.

Interestingly enough, Ana Beatriz appears on page 12, while her sister Patricia, a long-time interest of this blog, has this arresting ad for Guess? on page 3 of the same issue. Choose the sis you prefer!
