MIAMI BEACH, Fla. – The Kardashian sisters have gone from reality TV stars to designers.

The three teamed up with Beach Bunny Swimwear – which they sell in their stores – and designed swimsuits shown during the brand’s recent runway show as part of the Mercedes-Benz Fashion Week Swim 2011.

“Even though Beach Bunny has its own established collection, we each wanted to make sure we put our own twist on it and each were separated by our own personalities,” Kim Kardashian said before the show.

She said her designs were more glamorous, with jewels. Her sister Kourtney Kardashian went with the nautical look, while Khloe Kardashian Odom said she wanted “fun, but a lot of coverage but still really young and sexy.”

Her favorite was a gun metal one-piece that looked as if it had been shredded.

Gold hardware, hot pink and turquoise were all over the runways at the Raleigh Hotel in South Beach. There were also many bikinis and cutout one-pieces.

The shows preview the 2011 collections for retailers, editors and stylists.

Beach Bunny Swimwear

Beach Bunny Swimwear’s themes were old Hollywood, nautical and safari.

There were many bikinis and cutout one-pieces. A turquoise bikini was embellished with beige lace. A champagne-colored cover-up was embellished with hardware. A white bikini was decorated with lace.

A model strutted down the runway in a purple snakeskin print cutout one-piece.

A short orange shirt with a smocked waist was paired with a navy zig-zag-patterned bikini bottom. There was also a navy zig-zag print dress. Another look was a black cutout one-piece dubbed the “bondage” swimsuit.

White Sands

White Sands designed suits with high-waisted bottoms and halter tops, inspired by the 1950s. But cutouts reigned supreme at this line.

A one-piece with straps that crisscrossed at the neck had a black and white animal print. A high-waisted one-piece cutout with a tropical floral print was embellished with a hot pink bow on the chest. There was also a black and white lace pattern on a one-shoulder one-piece with a cutout.

Ed Hardy

Designers channeled 1950s pinup girl Bettie Page as they sent models down the runway. Most models wore a large flower in their long, flowing hair at Ed Hardy. A strapless one-piece had see-through bands of material in the front and back, giving a peek-a-boo effect. There was a bikini in white and gold. A lime green bandeau bikini had hardware on the sides. Colors included hot pink and turquoise along with the brand’s signature tiger and rose tattoo prints. A black bustier with studs topped black bikini bottoms.

“I think the common theme within the whole line is shine, metallic,” said Angela Avanesyan, one of the designers. “Ed Hardy is all about embellishment. It’s loud. It’s out there. That’s the brand.”

Naila

Swiss designer Naila Chbib said her men’s collection was all about nature. She had geometric prints along with solid colors on her men’s suits. Pink swimming shorts with a geometric pattern were paired with a white shirt with the sleeves rolled up to reveal the same pink pattern on the cuffs. She said her client is “a sporty guy. Very international. Well-educated.” Her lengths included long shorts, briefs and culottes.
