dress codes are permissible. "So long as [dress codes] and some justification in commonly accepted social norms and are reasonably related to the employer's business needs, such regulations are not necessarily violations of Title VII even though the standards prescribed differ somewhat for men and women." In Ulane v. Eastern Airlines Inc. 742 F.2d 1081 (7th Cir. 1984) Karen Ulane, a pilot who was assigned male at birth, underwent sex reassignment surgery to attain typically female characteristics. The Seventh Circuit denied Title VII sex discrimination protection by narrowly interpreting "sex" discrimination as discrimination "against women" [and denying Ulane's womanhood]. The case of Price Waterhouse v. Hopkins 490 U.S. 228 (1989), expanded the protection of Title VII by prohibiting gender discrimination, which includes sex stereotyping. In that case, a woman who was discriminated against by her employer for being too "masculine" was granted Title VII relief. Oncale v. Sundowner Offshore Services, Inc. 523 U.S. 75 (1998), found that same-sex sexual harassment is actionable under Title VII. A gender stereotype is an assumption about how a person should dress which could encompass a significant range of transgender behavior. This potentially significant change in the law was not tested until Smith v. City of Salem 378 F.3d 566, 568 (6th Cir. 2004). Smith, a trans woman, had been employed as a lieutenant in the fire department without incident for seven years. After doctors diagnosed Smith with Gender Identity Disorder ("GID"), she began to experience harassment and retaliation following complaint. She filed Title VII claims of sex discrimination and retaliation, equal protection and due process claims under 42 U.S.C. § 1983, and state law claims of invasion of privacy and civil conspiracy. On appeal, the Price Waterhouse precedent was applied at p. 574: "[i]t follows that employers who discriminate against men because they do wear dresses and makeup, or otherwise act femininely, are also engaging in sex discrimination, because the discrimination would not occur but for the victim's sex." Chow (2005 at p214) comments that the Sixth Circuit's holding and reasoning represents a significant victory for transgender people. By reiterating that discrimination based on both sex and gender expression is forbidden under Title VII, the court steers transgender jurisprudence in a more expansive direction. But dress codes, which frequently have separate rules based solely on gender, continue. Carroll v. Talman Fed. Savs. & Loan Association, 604 F.2d 1028, 1032 (7th Cir.) 1979, has not
