Bad quality

I am so disappointed with the quality of the gown I bought, I bought the same gown in Jan 2020 which was a very good quality, I was impressed and ordered another one thinking I will get the same quality but it resulted to money wasted. it is no where close to the quality I previously received and the money I spent is not equivalent to the gown I received. I want a clear solution of how we will sort this matter because I cannot spend so much for such *******.
