The era of falling clothing prices is ending.

Clothing prices have dropped for a decade as tame inflation and cheap overseas labor helped hold down costs. Retailers and clothing makers cut frills and experimented with fabric blends to cut prices during the recession.

But as the world economy recovers and demand for goods rises, a surge in labor and raw materials costs is squeezing retailers and manufacturers who have run out of ways to pare costs.

Cotton has more than doubled in price over the past year, hitting all-time highs. The price of other synthetic fabrics has jumped roughly 50 percent as demand for alternatives and blends has risen.

Levi Strauss & Co., Wrangler jeans maker VF Corp., J.C. Penney Co., Nike and designer shoe seller Steve Madden plan increases.

Cotton prices have jumped to a 150-year-high, rising to $1.90 per pound, more than double what it was a year ago and just ahead of the $1.89 record hit during the Civil War, according to the International Cotton Advisory Committee.

Raw materials account for 25 percent to 50 percent of the cost of producing a garment. Labor ranges from 20 percent to 40 percent, depending on how complicated it is to make.

On the production side, many Chinese factories that shut down temporarily in the depths of the recession still haven't returned to capacity, the Associated Press reports.
