If you're like me and only wear four or five of the 25 pairs of jeans you own, this could be good for you.

If you bring in a pair of previously loved denim to Barneys, they'll recycle them -- through 1 Percent of the Planet, an alliance of businesses committed to creating a health planet -- and give you 20 percent off your next pair.

Offer runs Saturday, August 1, through August 31 at Barneys CO-OP, 2209 Halsted, and Barney's New York, 15 E. Oak. The deal's only valid on full-priced denim for men and women. Brands at Barneys include Helmut Lang, Levi's Capitol, J Brand, Citizens of Humanity, 7 for All Mankind, Ever, Rag & Bone, Stella McCartney and more.

DESIGNER SALE
In addition to the denim offer, all Barneys New York locations are having their Designer Sale -- 70 percent off all summer merchandise. Sale is also offered online. A few standouts from the sale: A 3.1 Phillip Lim silk tank is $98, on sale from $150. Stella McCartney skinny jeans are $109, on sale from $325. For the men, a $198 pair of Citizens of Humanity denim is on sale for $79.73).
