Swedish model Alice Kastrup-Moller models the biggest retro fashion trend of the year, the see-through blouse. Even British royal Kate Middleton has dared to go sheer.

Moller was photographed by Filippo Del Vita for Creem magazine in the ’70s retro-style fashion. The look emerged among rock royalty in 2009. Madonna, Katy Perry, Rihanna, Lady Gaga, and Beyonce have all sported the see-through look.

Singer Gwen Stefani was spotted wearing a sheer black blouse with a red bra at L.A. Airport earlier this year. In fact, the list of celebrities going with and without bras is long and seems to be growing longer.

Everyone from 50-something Sharon Stone to 20-something Kristen Stewart has wore the revealing fabric. Even, underage UK “X-Factor” contestant Amelia Lily wore one recently. The 17-year-old was spotted wearing a see-through black blouse and mini-skirt on a casual outing at SoHo House in London.

Sheer fashions are even showing up at formal events. “Dancing With The Stars” pro dancer Karina Smirnoff wore a see-through blouse at the First Annual Winter in Venice Celebration in Las Vegas.

UK Actress Elizabeth Hurley wore a sheer Indian sari to a black tie event in London without the traditional sari blouse or a bra underneath. Then-husband Arun Nayar was on her arm, and seemingly unperturbed about her full reveal.

Actress Mischa Barton also attended a gala dinner after the opening ceremony of the 14th Shanghai International Film Festival in June. She wore a see-through blouse even though the even was held in conservative Shanghai, China.

Pussy Cat Doll Nicole Scherzinger attended Nelson Mandela’s 90th birthday party, wearing a daring, see-through lace blouse.

Of course, in clubs, the look is rampant. Olivia Munn was spotted in a dress and see-through blouse at the Marquee Nightclub Las Vegas Grand Opening. Her granny bra underneath drew hoots from fashionistas.

Lindsay Lohan jumped on the trend in January at West Hollywood club Voyeur, wearing a trilby, sheer black leggings, sky high heels and a see through polka dot blouse, sans bra, of course.

Christina Hendricks was spotted during Mercedes-Benz Fashion Week in New York in a see-through, lacey black top that revealed her ample breasts. Fortunately,she wore a bra.

And in what many consider a fashion faux pas, the 29-year-old Duchess of Cambridge was also seen in a sheer blouse, at a wedding, no less. She showed some modesty with a jacket and a strategically-placed diamond broach just above her waist, but still revealed a lot of skin.

Then again, these days, there seems to be no such thing as a lot of skin. Check out Alice’s photos.
