I am new, and this is my very first post, so: hello everyone!

I've been looking for a grey cardigan for layering (mostly at school). I noticed that Ann Taylor is offering 40% off of any one regular priced item for the next three days, so I took at look at their cardigans.

I am wondering if anyone thinks one of these is better than the other, or wants to recommend something else entirely:

Option A seems good, except I am worried that I would always have to wear it belted:

And I am worried that option B is a little too unstructured for me to be comfortable in, but it's hard for me to know because they only show it styled one way:

Any thoughts?

Thanks!
