NEW YORK (CNN/Money) - If it ain't broke, don't fix it -- and perhaps no one knows that better than executives at the Gap.

Some serious fashion fumbles like rhinestone-studded jeans and turquoise blue leather pants caused the retailer to stumble.

But with a return to basics led by CEO Paul Pressler, who took over after Mickey Drexler retired in 2002, the king of khakis is once again chugging along.

Last month, Gap posted its 20th consecutive month of positive sales growth. Wall Street rewarded the company handsomely, with its stock near a 52-week high.

But the test now is for the retailer to prove that it can stay the course.
