DENVER (AP) — A growing movement to remove laws against women going topless is headed to court in Colorado.

A lawsuit filed Tuesday challenges Fort Collins' indecency code, which makes it a crime for women but not men to show their nipples.

The Fort Collins City Council voted last year to retain its ban on women going topless, rejecting a growing movement to remove gender-specific indecency codes. The college town did make an exception for nursing mothers.

Other cities, including Denver, Boulder and New York, have removed gender-specific language in their indecency codes.

But a federal judge in Chicago recently ruled against a woman challenging that city's law against women displaying nipples.
