Love this top so much I got the white one as well.  Not sure why it says it's Plus Size, I am a size medium (5'4"/135lbs) and it fits great.  I wear it with my pajama type pants I bought on here as well and it's the cutest and most comfortable outfit.  I have been living in these clothes all summer b/c it's so hot in texas, I need loose flowy outfits to stay comfortable and cool.
