New with tags wedding dress

i bought this dress on May 5th 2017. It's absolutely beautiful. it's a size 8 but it's been altered to make it a little smaller. I, just got married on July 16th and on July 15th, yes the day before my wedding, in a moment of craziness while walking at the mall, i passed by one of those Chinese store and bought a wedding dress on the spot. So, I never ended up wearing this one. it still has the tags attached and i have the receipt. It was $1,300 but i got it for $650 and paid $325 in alteration
