Kate Upton Wears Pants! Plus Sexy Celebs in Their Most Conservative Outfits [SLIDESHOW]

Kate Upton wears pants! The Sports Illustrated swimsuit model isn't all sheer dresses, bikinis and topless horse-riding videos, after all.

Kate was out and about filming her movie "The Other Woman" with Cameron Diaz and Leslie Mann. In July, she was spotted in New York City looking like a stylish 21 year old. The Vogue cover girl looked fresh and quite conservative in a white, button-down shirt, floral trousers, and black pumps. Shortly after her turn in conservative clothing, it was back to sexy for Kate Upton. Bra-revealing, sheer, and skin-tight described her next outfit of choice.

Kate isn't the only sexy celebrity who dabbles in modest attire. Joining her on the list are daring dressers Miley Cyrus, Rihanna and Taylor Momsen.

Miley Cyrus, bra and belly-baring fan, showed a more covered-up version of her edgy style when she celebrated her Cosmopolitan cover. In February 2013, the "We Can't Stop" singer wore something white and long! Her Margiela outfit was sleeveless, but Miley threw a leather Moschino jacket over the pleated skirt number. With a major Medusa pendant necklace from Versace, Miley's white dress and jacket still felt very much within Miley's fashion sense, without resorting to belly-baring tops and dangerously high hemlines.

Taylor Momsen, Pretty Reckless singer and former "Gossip Girl" actress made a name for herself in the realm of daring dressing. The 20 year old's signature look is comprised of raccoon-level eyeliner, leather jackets, bra tops, platform boots and the shortest mini skirts imaginable. But, if Kate Upton wears pants, Taylor does, too! The former Material Girl model wore a conservative outfit for an unlikely event. When Donatella Versace relaunched Versus - Versace's younger, yet equally sexy line - Taylor turned up in a blazer and pants. Sure, they were blingy and showed a flash of midriff, but for Taylor, this was a surprising amount of fabric!

She may be known for swimsuits as outerwear, see-through outfits and dating Chris Brown, but Rihanna can dress like a young adult when she chooses to. The "Stay" singer, who recently wrapped her Diamonds World Tour, looked casual and fresh-faced when she was snapped at an airport in July. The pop star rocked a simple, white tee, Rihanna for River Island skinnies and black Balenciaga sneakers. Just to make sure she wasn't mistaken for a random college student, Rihanna wore a custom Givenchy cap.
