Scarves are a nice way to bring in a pop of color without putting aqua blue across your giant tummy which is bad news, baby. I've found full sized scarves to be a problem, as they can add bulk to the front of you if they hang down or can make your head look like it's going to explode if you wrap it too closely around your neck. There are so many nice, airy, handmade scarf options now, like this nice, crochet floral lariat. Go light.
