A new dress that has never been worn

An extremely nice dress, I only tried it on once I bought it for my brother's wedding, but alhamdulillah the bride's sister posted a photo of her dress and it turned out to be the exact same dress, so I went and bought a different one Note that I added external sleeves, which can be removed by a tailor The dress size is 20, fits XL, and you can take it in smaller I bought it for 600, but I'm selling it for 400 or 350
