Jean queen!

Kim Kardashian ditched her usual glam skin-tight getups for a casual, yet chic ensemble in NYC on Tuesday.

The Keeping Up with the Kardashians star stepped out in a fall-ready outfit of ripped-up bell bottom jeans and a billowy white blouse. She topped off her flowing dark hair with a tan beret -- an accessory you definitely don't see everyday on the 30-year-old.

Kardashian's laid-back look was perfectly chic for hitting up the Children's Museum of Manhattan with her sisters Kourtney and Khloe, Scott Disick and nephew Mason.

"Having such a fun day with Mason and my sisters! Wooohooooooooo," Khloe tweeted during their outing.

While Kim moved to NYC with her new husband, NBA player Kris Humphries, back in August, the rest of the Kardashian klan is in town to promote their new clothing line, Kardashian Kollection for Sears.
