Colorful Sheath Dress Size 14

I bought this Hannah Hardy dress because it reminded me of the Partridge Family bus and made me smile. I didn't smile given I never fit into it. Never worn. Doesn't have official tags but plastic that tags were attached to is affixed. Size 14. Small waffle-life pattern. 65% Cotton. 35% Poly. 100% Acetate lining. Small stain on front in orange and red blocks. I think it may be ink. Was on at purchase but never tried to get it out since it didn't fit.
