Minty Matrimony

A friend of mine is getting married this spring and I have already begun searching for the perfect ensemble. 
I was inspired by Gwyneth Paltrow's simple, stunning look at the Academy Awards. 
Clearly, I do not want to wear white...That would be a huge faux pas! 
I want to channel her classic, simple look.  Instead of white, I was thinking mint green.

Here are a few dresses I'd like to try.

I am thinking a fun ponytail for my hair... and a spray tan of course.

Any suggestions for minty frocks?
