What to Wear

I'm supposed to be sleeping at this moment since I need to wake up later at 1PM for a Weekly Ops Meeting at 4PM. However, I cannot sleep because I was pre-occupied by the thought of what to wear on my friend's wedding next month.  

She chose me as one of the Secondary Sponsors on her wedding day. Motif is Olive green (hopefully it would fit my skin tone @_@). I was browsing a wedding site earlier and found these: (my top 3 choices but I think I would really go for the first pic. LOL)

To my blogger friends, just want to get your opinions. Which one would you think will suits me? Any suggestion is highly appreciated.
