Aéropostale fans can take heart from this week’s news that the teen retailer is doing better than expected after its recent Chapter 11 filing. About 500 of Aéropostale’s 700 stores are making money, the company says, and those will likely remain open despite the “going-out-of-business” signs plastered across their windows. That’s good news for the Aéropostale store at Westfield Montgomery Mall, which is said to be one of the solid performers.
