Reporter: But the twosome now find themselves on opposite sides of a nasty battle of the brands, after chris burch started a competing mall brand called c. Wonder this year. Don't believe the tory burch company has a monopoly on bright-colored sweaters. Reporter: Tory burch disagrees. And the two are involved in lawsuits and countersuits. She says he stole her secrets. This is tory burch on the left and c. Wonder on the right. Industry insiders say it's not just the new store's decor at issue, but the products they're selling.

I don't believe tory burch customers who are looking at spending $400 or more for a sweater, are going to be looking at c. Wonder and vice versa. Reporter: "Vanity fair" talked with chris burch for its december issue. And size while the ex-spouses may be battling each other, the fight won't hurt either of their fans.
