Kendall Jenner's fashion staple is a pair of jeans.
The 'Keeping Up With The Kardashians' star thinks every girl should own a pair, whilst sister Kylie Jenner's essential garment is a leather jacket.
Of her go-to gear, the 19-year-old model said: "A pair of mid- or high-rise jeans that look good on the butt, with straight or skinny legs."
Whilst Kylie added: "A good leather jacket. Everyone needs a good leather jacket."
And Kendall has admitted she likes to keep her day wear "simple" compared to Kylie who prefers a more glamourous look.
She shared: "I like to keep it simple and classy. I'm not like [Kylie]. She can wear a full-blown gown to lunch. I like a whole Saint Laurent look. I'd call it cool."
And despite being known for their fashion-forward looks, it hasn't stopped either of the pair having a fashion faux pas in the past.
Of what pattern she'd never wear again, Kylie said: "Zebra. Growing up, I was obsessed with zebra. In middle school, I had zebra carpet, pillows, and clothing - everything you could imagine.
"So I am zebra'd out. I don't care what company it is or who it is, I'm over zebra."
However, Kendall is much more open to different styles as fashion "evolves".
She added to Harper's Bazaar magazine: "I never say never. Fashion is always evolving. And you just never know."
