Catherine, Duchess of Cambridge has worn a lot of very conservative looks during her North American tour with husband Prince William.

She’s also worn casual looks as she’s been spotted twice wearing J Brand jeans, which appears to be her favourite brand when it comes to denim.

Today she was spotted about to board a jet to Slave Lake at Yellowknife Airport wearing her navy Smythe blazer, navy luxe twill J Brand “811” mid-rise skinny pants and Nine West Cheyanne wedges.

Yesterday the same pants with a Burberry shirt on a visit to Yellowknife, Canada.

On Monday she competed in a dragon boat race with William wearing the same jeans.

Yep, she’s worn these J Brand jeans 3 days in a row.

The last two looks were paired with Sebago Bala shoes, which mean she packed at least 5 pairs of shoes for this trip including her much loved L.K. Bennett nude pumps, the Tabitha Simmons pumps and navy Prada pumps.
