Did Mom Kris Approve? Kylie Jenner, 17, Steps Out In JUST Denim Shirt And Thigh-High Boots!

Is Kylie Jenner growing up too fast? The reality star teen went shopping with friends in New York City’s trendy Soho neighborhood in an oversized denim shirt, high-high leather boots and edgy fingerless gloves on September 5. The outfit was certainly inappropriate for the weather— It was 88 degrees and humid in NYC— but it also seemed to be all too much for a girl who just turned 17 last month.

Sister, sister! Jenner’s new hair extensions make her look just like big sis Kim, 33.

She’s very confident: Jenner and big sister Kendall, 18, recently debuted “selfie” tee-shirts of their own faces for PacSun.

Too big! Jenner’s denim topped looked even too large for dad Bruce!

Bad to the bone? She toted a skull print scarf and gold jewelry as she headed into the store.

Changing it up: She sported a different denim shirt just hours before.
