It seems to work synergistically for me. I edit regularly (and at least twice a year I do a big edit) and have noticed it can go either way. For instance, when silhouettes (or my preferences for silhouettes) are changing, I might edit a worn piece and then find myself shifting style direction. E.g. I weed out a worn out tube skirt (narrow bottom) and find myself not needing longer tanks anymore because I'm wearing full skirts with tucked tops. OTOH, it could work the other way, e.g. I buy a pair of wide leg pants and then begin using my "tuckable" tops more often and end up editing the ones that don't fit this role.
