The answer to that question is varies from person to person..... jeans with a smaller hem, such as 19cm and 17.5cm diors, thanaz, thin finn, nc, etc look better stacked than say.... a new standard cut. Shorter people get the chode look with lots of stacks sometimes. I personally wear mine like you describe, some bunching, not "stacking", enough so where my sock isnt exposed if im wearing a high top or boot. I think too much stacking looks immature anyway.
