BHLDN Peter Som Olivia Dress Spring unclassified dresses

I bought this dress at a BHLDN sample sale. I can't remember what the actual listing price of this dress was, something between $2000-3000, and possibly more. I paid $300 for the dress with the possible intentions of wearing it at my own wedding. However, I was unable to try it on at the time I purchased it, since it was quite a grab and go event. The label size says 8. I wear a dress size 6. I thought i'd have no problem fitting into it. I was totally wrong. This is really more of a size 2 dress. I could zip it up to the waist, and then needed about an extra 6 inches to get the girls to fit. I think this dress would be great on someone who is a size 2 with a c cup or less, or a size 4 with a b cup or less. I am a DD, so I had no chance. The dress sat around for months, and then I decided to use it for a photoshoot that my floral company was doing. The model wore the dress for maybe 2 hours and that is the extent of it's use. It's a beautiful dress, and I could probably get more money for it, but at this point I have been holding on to it for a year and a half and I just need to get rid of it. As far as issues with the dress... It needs to be cleaned. I haven't wanted to spend the money to get it cleaned because I don't care to keep it, which is also why Im asking less for it. There is a minimal amount of dirt in a few places on the bottom from the photoshoot. I'm positive it would clean up very easily. The straps are extremely thin and look like they may have slight discoloration due being worn, but would also probably clean up easy, could be replaced or could be taken off for a strapless look. Please feel free to contact me if you have any questions, or would like additional photos of the dress.
