It's hard to find pretty silk blouses other than pussy bow ones lately but as a large-norked small person, pussy bows are never going to be my friend.
If you can ignore the fact that the model looks like she wants to bite somebody's ears off though, I think that this could well be a contender. Has anybody seen it irl? I have a v similar one from last season but in a more delicate print and it is proving very useful.
