If you have a Chadwicks (of Boston) account card, it's good at Lane Bryant and Jessica London and Roaman's (other "plus-size" clothing catalogues). Does that make all of them part of Limited Brands?
It's kind of like the Evans/DP/Burton/Bhs/Wallis/Topman/Topshop thing here. A card from one of them is good at all of them.
