In Susan's show now, I sort of like this cardigan and tank in a couple of colors, but they all have black tanks except for the blue. I might be tempted to get the green and the merlot - but I have a black tank already as well as other black tops, so I don't need two more black tanks.
Why on earth would she not put tanks to match the cardigans? I do buy multiples if I find something I really like, but I wouldn't buy something with multiples of the same color!
