It is nearly impossible to sum up Jennifer Lopez's personal style in a short sentence. But one thing many of her looks have in common is that she wears fine blue jeans (and a white Birkin, but that's a story for another day).

This pop star loves the denim trend, but rarely sticks to the same cut. One day it's 70s flares, another day it's cool distressed skinny jeans for the first time in a decade, the puffy, pleated style that dominated the hipster scene in 2012.

In August, the “Let's Get Loud” singer revived this denim trend in a dark-wash wide leg. And this week, Lopez is at it again. Lopez was spotted in Los Angeles on October 21 wearing a cloud blue turtleneck with a pair of tapered pleated jeans in a similar color (photos available at StarStyle). 5]

Heralding the start of fall, Lopez added an unexpected twist to her all-blue color story by pairing it with lots of chocolatey suede. She finished off her favorite suede crossbody (a slouchy hobo style) with a pair of designer hiking boots. Specifically, she opted for Brunello Cucinelli's $1950 boots.

Pleated or not, Singer tends to gravitate toward loose-fitting blue jeans; in July, she paired long-line jeans with a paper bag waistband with a sleek white blazer. She's also a repeat customer of Gucci's Puddle Jeans, which she pairs with everything from crop tops to oversized jackets.
