XP: This dress with our colors?

heyTiffany

So one of our "accent" colors is silver. BUT this dress looks more gold to me. If I get this, should I change the accent color to gold? I think it'll look better (our other colors are navy and yellow - if the BMs wear navy, will gold shoes look okay?) We haven't bought anything yet so I have time to play with colors, which is why I'm asking.

Can I wear silver jewelry? Or should I do pearls?
