quick (fashion) questions: what do you buy over and over, and why?

calvin klein denim jacket
(one of my obsessions, of which i have multiples: denim jackets!)


what do you find yourself purchasing (clothing/accessories, etc.) over and over, and why?
are there certain items that you have multiples of in your closet?
what characteristics do they have?
what do those pieces mean to you? i.e., what do those items symbolize or represent to you, if anything?
do you wear these collected items, and keep them in heavy rotation, or do they just sit there, unworn?
