Abercrombie & Fitch (Abercrombie.com)

Preppy retailer Abercrombie & Fitch refuses to sell clothes for women who wear a size large and above, despite statistics showing that the average American wears larger sizes, reports Business Insider. This is the same company that's faced criticism for T-shirt slogans that many Asian Americans found racist back in 2002.

While a specialty retailer like Abercrombie can't be expected to appeal to everyone, the brand's standard of beauty is quickly becoming stale. 

Plus-sized is no longer a niche market: 67 percent of the apparel purchasing population fit that label, and the number is growing all the time.

Ignoring this "revolution" could be costly for businesses, Bogenrief writes. 

More brands are featuring curvy, "real-sized," models.
