Material shader is very reflective when rendered

I have an image that when I render it one of the articles of clothing on one of my characters is acting weird.  I have rendered this character in other scenes with no issues but with this one her top is completely washing out and is bright white.  Almost like it is reflecting the surrounding light and not showing the blue like denum of the material.  What could be causing this?

Which outfit? Which render engine?
