I bought a dress (used) in good condition, but, the darts are sewn on the outside of the dress, overlocked with threads hanging off and the back zip is sewn in on the wrong side of the dress. When I first got it, I thought that it was inside out, but the side seams are sewn the correct way. The seller claims that this is a design feature of this 'very expensive' dress, which I bought cheaply.

It may well be a design feature, but was not mentioned in the listing and I think if it is a design feature, it is quite a different feature and should have been mentioned. I have looked at the photos again and now that I know the dress has an inside out look, I can tell, if I zoom on those parts, but I would never have thought to check whether the  darts and zip have been sewn on the right side.

She has refused the return and accused me of buyers remorse and is very insulted that  I didn't like her 'very expensive' dress.

I could never wear it. People would look at me and think 'that poor old lady has her dress on inside out'.

I have never returned anything before.

What to do now?
