Lady Sonia, какую блузку мне носить

I have just bought to new classic sheer silk blouses and as I am going out this evening I want to put them both on so that you can help me to decide which one I am going to wear together with fully fashioned nylons and my classic black under-bust bodice. Should I open a few buttons? Do they show off my bust as I walk and move? Is this one a little too see-through? Will you help me to choose?
