Celtic Irish Traditional Folk Step Dance Solo Dress Costume Shiny Purple Girls. The waist is 13" across when laying flat.  The back of the neck of the dress to the bottom is approximately 32" long.  From under one arm to the other when laying flat it is approximately 15.75" across.  Please ensure the dimensions will fit as there are no returns.  The only issue I see is that the INSIDE looks like it could be cleaned around the top and there is one mark on the sleeve, the very end of the cuff as noted in the last photo.  There is some hair in the Velcro on the back unfortunately.  Not sure how to remove it.  Please see the photos as they are considered part of the description.
