Kim Kardashian, 'Jersey Shore' Star J-Woww, Others Reveal Their Fashion Must-Haves

'Earrings! I have chubby ears, so I gotta wear my earrings,' Jenni 'J-Woww' Farley said at New York Fashion Week.

There are fashion choices that people regret and then there are the go-to outfits in everyone's wardrobes that prevent them from making such fashion faux pas. As these celebrities point out, it's all about having the right basics in your closet — like the staple little black dress — to ensure that you always look your red-carpet best.

"Earrings!" "Jersey Shore" star Jenni "J-Woww" Farley told MTV News about her fashion must-have. "I have chubby ears, so I gotta wear my earrings."

While earrings are the choice accessory for J-Woww, "Keeping Up With the Kardashians" star and Bebe fashion designer Kim Kardashian said it's all about having the right blazer. "I can't live without a black blazer, and I think that you know you can wear it with a dress or you can wear them with a T-shirt and jeans," she explained. "It's just super-chic."

Singer Estelle's fashion advice was very simple: "A good pair of jeans and a good pair of Spanx."

And fellow Brit Kelly Osbourne seems to agree on keeping it simple. "You can never do without a simple black jacket, a good pair of jeans, great heels and a good bag," she told MTV News. The former MTV star previously shared her one big fashion regret, saying, "For some reason I kept pasting my face even whiter, and I had this black eyeliner and this green dress," she said. "Every time I see the picture, I'm like, 'Ewww.' "

Like Osbourne, Kardashian has a few skeletons in her fashion closet too. "I was so matchy-matchy," Kardashian said. "I probably regret wearing this turquoise sweater with these turquoise flowers in my hair and turquoise eye shadow."
