I don't wear cardigans often but do like to have a few in my arsenal. I was looking at cardigans today and I have so much trouble getting them to lay right. They always want to fall open and lay down the side of my chest, rather than nicely lay down the front of me. Am I explaining myself clearly? Is it the style (I've been trying for v-necks) or do I need to size up? Does anyone else experience this? Anyone have a solution to this problem?

I am suspecting now that I think about it that it could be a combination of the long cardigan and v-neck... perhaps the weight of the cardigan is pulling the whole thing open too much?
