Help! What to wear to my class reunion?

I'm having a hard time believing it myself, but I'm attending my ten-year class reunion on Saturday!  How is it possible that I graduated from high school ten whole years ago?!  I'm feeling pretty excited to spend some quality time with good friends and to catch-up with acquaintances I haven't seen in a decade.  Before the festivities begin, however, I need your help!  What should I wear?

After trying-on countless dresses, I have narrowed the choices down to three frocks:

LOFT

LOFT

Target

Which would you choose and how would you style it?  Let me know in the comments section!  I will let you know which dress I chose next week!
