ISO size 2 Carven dress - open to TRADE for size 6

I got this dress in too large a size and can’t return. I am looking to trade for the same dress in a smaller size or potentially a similar and equal quality dress. Would be open to purchasing the smaller size without trading for the right price Dress retails for $700+, Carven 2017. Beautiful quality, NWOT. This is size 38, which is about a US 6. I am looking for a US 2 (ideally) or 4. I will cover shipping for both for a trade. Please message if interested!
