Personally, I really like the look of a button down cardigan with a simple dress shirt and tie. In fact, currently I'm wearing a navy cardigan, white dress shirt, checkered tie, and dark jeans. I've heard people scoff at wearing a tie with a cardigan, but I'm still not sure why.
What do you think about the outfit in the picture below? I know there's not much to it, but there are some diehard cardigan w/ tie haters out there.
