Yeah - it's really just common sense but easy to overlook re: proper silhouette. It probably doesn't occur to mostly everyone as they first start building a wardrobe. You don't want some full cut suit and then a really narrow shoe or vice versa. If you want a tapered jacket then the reast of the outfit should reasonably match it. There isn't a whole lot more to it than that.
