About ten suits and jackets per season for a basic working wardrobe in which a man wears tailored clothes throughout the week. That is not a giant wardrobe: that is a basic one. If you are favored living in a climate that has but one or two seasons, then you might have chance at a wardrobe of ten to twenty items...one or two of which you will replace every year. If you live where there are real summers, falls, winters, and springs...well, Mother Nature has condemned you to a bigger closet. Thirty or bust. - B This.
