Prom Dress/Ball Gown

I only wore this dress once. It is a PC Marys Queinceanra. The dress is a saphire blue with a lot of beading and design. It is strapless and full length. It poofs out like a princess ball gown. I bought the dress for $423.95 and I have the reciept. I am asking $300.00 for the dress. It is in great condition. This was my dream prom dress and I hope someone else can say the same.
