Return

[euro-666]

Hi, I purchased a dress, but the seller provided misleading sizing information. I want to return the item, so I opened a case for a refund. However, the seller closed the case, and eBay has not been helpful.”

If you use the reason 'wrong size/doesn't fit' then that counts as a change of mind request and private sellers do not have to accept returns.

You needed to open a case using the reason the item was not as described.

You can try your payment source and start a chargeback on the grounds you bought an item online which was misdescribed.
