I want to order an impressions BM dress in iridescent taffeta. I looked at the one inch swatches at a store, and the espresso color seemed to have a nice copper shimmer to it, but I'm worried it will look different as a whole dress, like just blah brown. Has anyone seen this color and fabric in real life? The Internet color swatches are useless and look nothing like the real thing, at least in this case. I know this is ridiculously specific, but i thought I'd ask anyway.
