WIP Crochet Executive Barbie

In May, I started to work on crocheting an executive outfit for barbie.  I am planning to eventually make a pattern of it once I have had a chance to tweak it and all that jazz...

However, I am looking for your lovely opinions...  I would like to make a briefcase, heels and perhaps a belt of some kind.  But I am not sure what colour I want to do for this set.  What do you all think would look nice with it?  Do you think there is something else this executive Barbie needs to go with this outfit?  Let me know your thoughts in the comments below...
