Can anyone ever have enough in black? This is a super cute ruffled, tie at waist blouse. The material is a light, stretchy, crinkly detail that is so feminine. What doesn't black go with? This could be styled so many ways - could take is super dressy to casual with shirts and black sandals. The armpit measurement measuring across the front from armpit to armpit on the small is 19". The measurement at the waist is 18". Each size goes up in increments of 2". I am wearing the medium. I am 5'4 36" bustline.
