Sincerity 3836 Velvet unclassified dresses

I bought this beautiful off-the-shoulder wedding dress in 2018 after I got engaged and got married the following summer in June 2019. I got the dress length altered because it was way too long for me. I am 5' 7" and wore about 2.5-3" heels with the dress. I got the dress professionally cleaned and so it is all ready to go! The tag says that it is a size 10 but I wear size 8 for the most part, and the dress fit me perfectly (except for the length). I am the original owner and only wore this dress once on my wedding day! There are no tears, stains, or etc, dress is in perfect condition.
