Okay....
This is a silk printed skirt that I usually wear with a blue/white shell or a ivory turtleneck -- the jacket is a three button, no color, small lapel thinging:
 
This is the same jacket with floaty grey pants and a paisley print blouse with grey, cream, red an black:
 
This is the same outfit with the fab red jacket I found today:
 
This is my "standby jacket"  -- it is really pretty, kind of a pinky tan with pinky tan embrodery and pinky tan shell buttons.  These pants I found today are perfect with it -- kind of has an Asian vibe wich I really like:
 
I usually wear this white satiny peacoat when dressing up.  It doesn't look that nice here but it really is cool.
 
I also have a knee lenth black kind of floaty wrap skirt but it just seemed like a cooler weather outfit....  Still, it could be put into play.
I'm pretty sure that each of these outfits would be appropriate for the style of the event.
