I've been reviewing some of Angie's guidelines about body shape and fall transition clothing. I'm wondering what the best shape cardigan would be for hourglasses. One post said that the boxy, 50's style cardigan should be avoided.

My only problem is I've fallen in love with the claret color BR cardigan:

I also like a few of those J Crew cardigans (tartine, dream v-neck)
Now I'm wondering what I should be looking for in a cardigan. Can I wear a box cardigan as long as I button at least one button?
