I should have added that the skirt was ankle-length.
Here are some WTS comments on jeans:

Jeans Cripple Youth ยท
A Danish medical magazine recently told about an 18-year-old youth who was thrown into a bathtub during a party. Afterward, he went to sleep in his wet, tight blue jeans. When he woke up after 11 hours, he found that blood strangulation caused by the shrunken jeans had damaged his right leg muscles, crippling him for life. The doctor writing the article cautioned youths against buying jeans that are too tight and especially warned against shrinking them to be skintight by wearing them wet.

g99 2/8 p. 17 The Kind of Clothes We Wear?Does It Really Matter? ***In an article on students? perception of teachers, the journal Perceptual and Motor Skills explains that "although the teacher wearing jeans was seen as bringing fun into the classroom, his opinions were given the least respect and he was most frequently chosen as the teacher who does not seem to know anything." The same journal comments that "a female teacher dressed in jeans was seen as fun, approachable, not especially knowledgeable, commanding limited respect, not looking like a teacher, and generally preferable."

g89 10/8 p. 11 What?s the Secret of Choosing the Right Clothes? ***Millie, one of Jehovah?s Witnesses, attended a school where violence was prevalent. Dressing as if headed for a Christian meeting would have made her overly conspicuous. So she wore a modest pair of jeans during school hours, as that was accepted at her school. But since she engaged in Bible educational work after classes, she took along a dress. Change of role, change of attire.
Youths among Jehovah?s Witnesses give particular thought to what they wear at Christian meetings and in their public preaching work. For example, jeans and sneakers, which may serve quite well at school, are out of place during formal worship; they detract from one?s claim to being a minister of God.?Compare 2 Corinthians 6:3.

g87 2/8 p. 16 What Do Clothes Mean to You? ***Even on a more personal level, decisions must be made as to what to wear, and when and where to wear it. Dungarees, or blue jeans, may be ideal for farming or working around the house or on casual occasions, but they are hardly appropriate for formal occasions, for business, or at meetings for worship.
