What I meant was that denim in itself is now connected with goyshe forms of dress.
However, I will stress there is denim and denim. Some denim is washed out and looks worse than other denim. I should also like to add that denim skirts should be avoided whereever possible.
You also refer to style. Style of clothing is another matter entirely and people should not need to be told that the style they are wearing is appropriate or not – they should know better.
You mention that in your community jeans are enormal attire, please do forgive me here but that is not normal attire unless the person does not know that there is or should be a dress code for shul.
I do not like confrontation or offending anyone and as I do not know you or your community I will refrain from commenting further to you.
