Rails Silk Maternity button down blouse

Really pretty butterfly print button down blouse. 100% Silk. Wore it twice for my baby showers. There is a small spot of the lower left side. The dry cleaner must have missed it, because it looks like it will come out. I could get it cleaned again, but it would make me less flexible in my pricing. Spot is photographed in the 4th and 5th photos. Size L.
