Just as the title suggests. I'd like to know if it makes sense to have, for example, several grey blazers in different materials such as, cashmere, silk, cotton, linen and wool? To add another variable, I'd like to take weaves into consideration. For example, herringbone, twill, nailhead, birdseye and houndstooth. I haven't found anything on this topic while searching through the net. I would love to hear others input on this matter.
