Oh Polly sizes are too small, I think they do this so yours forced to return items for an exchange, once you get the correct size they will says you're outside the window to get a refund back. If you get a refund straight away they will find a reason why you can't have a refund. E.g tissue paper removed from dress which needs to be in order to try on the dress... But you can't have a refund still. I've been a customer for 5 years and oh Polly has changed, they don't care about loyal customers and it's turning into a scam. Recently I returned one order apparently there is a mark on one of the dresses, so they returned the whole order instead on just the one dress. This is all a tactic to delay the refund process and blame it on the customer so they can't get their money back. After my issue with the past 3 orders I will no longer be using oh Polly after 5 years.
