I have never heard of any such halacha...source?
I just looked up the source for this halacha in the book called, "Modesty-An Adornment for Life (Halachos and Attitudes Concerning Tznius of Dress & Conduct) " by Rabbi Pesach Eliyahu Falk.
On page 306 it list some reasons why it would not be recommended. Without getting into detail, it says: 1. In many areas such skirts are conspicuous 2. She appears to be copying the latest styles 3. Such skirts are not worn because of modesty.
Each reason goes in to extensive detail according to halacha.
For reason number three it says the following: "...it is incorrect to view them as exceptionally tznius'dik garments. ...it will be best understood by first referring to a strange phenomenon that was to be found at a time when Jewish women slipped to a very low level in tznius and were roundly admonished by Yashaya HaNavi."
"One of the items he [Yeshaya HaNavi] mentions that women wore at that time was a face-kerchief called a "Ra'alah", which hung over the face with just slits cut out for the two eyes. This is of course a mystery - how could it be that women who were prutzos wore an item as tsnius'dik as this? ...Rashi says in Yeshaya 3:19 'Women wore these kerchiefs which covered their faces inorder to provoke men and arouse within them a passion to see their cheeks.' As a result of this, when the kerchief would lift a bit due to the wind, the appearance of the cheeks presented an enticement to those who saw it. In other words this excessive covering was done to heighten the attraction of themselves, and was part of the unholy crusade that they had undertaken to entice and provoke men to desire and admire them as much as possible - see 6:J:2 below"
The sources for this book are written in a seperate sourcebook which I unfortunatly do not own.
It is a great book to strengthen yourself as much as you can in tznius. Tznius is a very complex halacha which deals not only with dress, but also in speech, behaviour, and social interaction.
Hope this gives some insight to your question.
