People are finally tired of skinny jeans, and women's designer jean sales dropped by 6% last year to $1.36 billion, Bloomberg reports.

That's a disturbing trend for everyone from Macy's (M) to True Religion Apparel (TRLG) to American Eagle Outfitters (AEO). They're all wondering about the next jean trend to jump on to recover those sales -- and now, they think the answer is in the flared look.

Macy's and Bloomingdale's are betting on $185 jeans from J Brand that look like upside-down martini glasses, Bloomberg reports.

"It's been a hit," the women's fashion director at Bloomingdale's tells Bloomberg. "We've all been wearing skinnies or jeggings for too long. It's a reason to buy."

What the retailers really want is a domino effect triggered by a flared-jeans purchase. Suddenly, a shopper will need a whole new set of tops to go with such a dramatic shift in jeans. The larger, flowing tops that were just right for skinny jeans don't look as good with flared styles.

American Eagle has a $50 "vintage flare," and True Religion sells flared jeans for as much as $319, Bloomberg reports.

And flared jeans will set off new shoe trends as well. Uggs worked well with skinny jeans, for example, but not so much with flared. Experts say platform shoes or sandals could be the preferred styles from now on.
