New unused bridal dress

Hello, I bought this veil from the brand Rosa Clara at The Zone. The original price of the veil was over 1,000, and after the discount, it became 900. The invoice is available as proof. I received it yesterday, but I felt that another veil would suit the dress better. Unfortunately, the store does not have a return or exchange policy. "The veil is unworn and unused." Selling price is 800, negotiable reasonably
