I needed a white button up blouse with a collar for a work uniform and I am a plus-size woman.  The princess seams make it less boxy, and the addition of a button or two prevents gapping at the bustline.  That is really what makes this blouse a 5 in my rating.  This blouse is extremely reasonably priced; I could not make the blouse for its price.  It is "easy care" and looking at the instructions for laundering the blouse, it does indicate light ironing as necessary.  Yes, it does come out of the dryer with noticeable wrinkles.  I found that if I hang it up after the rinse cycle, I can smooth the fabric out and can get by without ironing it - partly because I wear an apron over the blouse.
