The Harmonized Tariff Schedule of the United States is a 3,000-page book that classifies every single thing that enters the country, all for the purpose of determining how to tax it when it gets here. For example, black tea is free, but flavored green tea will cost the importer 6.4 percent. A T-shirt made of man-made fibers has a whopping 32 percent tariff, but if it's cotton, then it's only 16.5 percent.
The point is that how you classify something makes a big difference when it comes to paying taxes. Victoria's Secret, like most clothing companies, manufactures clothes overseas and then imports them. They make something called a Bra Top and another thing called a Bodyshaper. The Court of International Trade said these were "other garments, knitted or crocheted," which requires a 10.8 percent tariff. Victoria's Secret, on the other hand, says they should be considered "brassieres, girdles, corsets [...] and other similar articles and parts thereof." That's only 6.6 percent.
