P.S.Kate Black/white polka dot flair dress Size 8

P.S Kate black with white polka dot flair dress. Size 8. Very flattering V-neck with two buttons I. Back to create keyhole design. Dress is not lined, but it is not see through. Stretchy material. There is no size tag inside but I am a size 8 and this fits perfectly. Never worn other than to try on. From a non-smoking home.
