I purchased a Dunns wrap dress in the same print as a simple dress my daughter has so we could wear the same for funsies. It arrived and I immediately put it on only to find that it didn't cover my chest. Not just a little, I mean fully didn't cover my chest and just hung below all stretched out. I contacted the seller and politely tried to point out that it didn't fit only for them to basically say it's your problem, you sell it on. So I did the complaints process on vinted, it took them weeks, I sent photos of the dress on my dressmakers dummy with both small and large bust (padded a bra out), it still hung off the chest, if you wore it out you would be arrested for indecent exposure. They still ruled the dress was as described by the seller (very good condition and apparently worn twice), they gave her my money. I obviously left a review on her page which they took down and threatened me with banning my account if I wrote another review, apparently stating fact isn't something they want. I then tried to contact them again to be told that they wouldn't talk to me and if I carried on they would close my account. I have since contacted both trading standards and my bank, and am happy to report that I have got my money back. However, they clearly don't let people review others properly on the site, so we never really know what we are getting from them or how trustworthy they are. They take forever to actually do anything and in my case decided that a dress which is stretched so badly it doesn't cover someones chest is perfectly acceptable. I have attached a photo of the dress, it is tied as tight as possible to try and bring the front wraps up, it's just ruined.
Recommendation: Don't, just don't.
