When it comes to clothes, I believe in quality over quantity. So when it comes to leather you have to be prepared to make an investment. Cheap leather is a very bad thing (unless you enjoy being picked out of a crowd based on smell alone). But the good news is that a great pair of high quality leather pants will last years. And as an added bonus, they get better with age. This fall, leather pants and even leather shorts are emerging as a major trend. And though they can seem a little scary for first time owners, leather is a very versatile material that looks smokin’ for both casual and dressy occasions alike.

Here are a few of my favorite leather pieces for fall that are definitely worth the splurge.

Current/Elliot Leather Legging Pants, $795. Saks.com

Current/Elliot translates their flair for denim into an ideal leather pant. They are manufactured like a jean, but made of 100% lambskin leather. Just like your favorite denim, wear them day or night.

Helmut Lang Skinny leather Pants , $875. shopbop.com

Although this style is nothing new for Helmut Lang, they fit perfectly into the trend forecast of fall 2010. With butter-soft leather, an elastic waist and a smooth silhouette courtesy of faux pockets, you may never want to take off these ultra-flattering pants.

Isabel Marant Shun Cropped Skinny leather pants, $1,860. net-a-porter.com

French designer Isabel Marant has a serious cult following in the States. And since few retailers carry the line or keep it in stock, Marant’s pieces feel extra exclusive. These cropped leather  and cotton-lined pants are the epitome of Marant’s edgy take on femininity. And their shorter length makes them unique.

Alice & Olivia Leather-Paneled Riding Pants, $495. neimanmarcus.com

Alice and Olivia’s equestrian-inspired paneled riding pants are a great way to incorporate leather into your wardrobe if you’re a bit faint of heart. While less subdued than a full on black leather pant, they’re just as cool and feature a front zipper and a cool army green color that is perfect for autumn.

Vanessa Bruno Lambskin Short, $552. lagarconne.com

Vanessa Bruno knows how to make women look their best – chic, slender and feminine. And these lambskin shorts are a great twist on the current leather trend. Unlike their 1980s-inspired, high waist counterparts seen at hipster concerts all over town, these feel modern with their structured, tailored vibe. They work with a simple sweater and flats or heels and a chiffon blouse. Versatile and super-stylish.
