If you’re not the kind of person inclined to press your pants before that 8 a.m. class, you may want to avoid the Illinois State University College of Business. This semester, the college has instituted a “business casual” dress code for students enrolled in its marketing and business teacher-education courses, The Journal Star, a newspaper in Peoria, Ill., reported.

The idea behind the code is that students who dress professionally act professionally. Among the sartorial suggestions: khaki, corduroy, twill, cotton (all “neatly pressed”) on the bottom, and sweaters, polo shirts, cardigans, and twin sets on top.

“Inappropriate” garments, according to a letter to marketing majors from their department’s chairman, Timothy A. Longfellow, include jeans, overalls, shorts, “and any spandex or other form-fitting pants such as bike clothing,” as well as T-shirts, and “shirts with potentially offensive words, terms, logos, pictures, cartoons, or slogans.” Clothing that has the Illinois State University logo, however, is encouraged.

According to local news reports, the code is an extension of the college’s standards of professional and ethical conduct, which mention wearing appropriate clothing to class. But at least one student was uninspired. “It’s not like you need practice wearing clothes,” Todd Froemling, 22, told the Associated Press. —Beth McMurtrie
