Love this shirt but confused

I continue to think about this shirt from JCrew as a potential holiday office party option but I'm confused. There are buttons and button loops but they never show it closed. I suspect closed up, it may look a little Adam and the Ants 1982-ish so they continue the non-button option. Don't get me wrong I like it a lot, it's very Cate Blanchett as Elizabeth which I'm soooo down with. It's definitely an option.

The item I bought last year for my office xmas dinner has not been worn since. A lovely little pintucked women's tuxedo shirt. It's a great garment I just can't figure out how to wear it to the grocery store or on an ordinary day, hence the hesitation with said shirt above. Where does one wear taffeta after the fact? I'm still pondering and hoping whatever it is I end up with goes on super sale by the time the party rolls around.

Only prereq for the said item is it has to go with the Louboutins. but hey... what doesn't really?
