Is wearing "denim" fabric forbidden if it is tailored in a way that suits Muslim women, and is that considered imitation of infidels?

If this fabric is used in a manner that resembles the clothing of the disbelievers, then it falls under the category of imitation. However, if it is tailored in a way that differs from the clothing of the disbelievers, then there is no harm in that, as long as its appearance does not resemble what the disbelievers wear, even if they are well-known for this fabric.
