Multicolored sequin flapper dress NWT

there is no tag in this dress that I can see so I'm really unsure whether it's vintage or something that was purchased new but it's sold in a local vintage shop. I purchased it several years ago for an event that I never attended so it is in perfect condition and has been hanging in a garment bag in my closet all this time. it no longer fits me so I am turning it loose. at the time that it fit me I was between a size 10 and 12 with a 40D bra. downsizing my Cabaret and dance closet. some of my pieces that I'm listing are vintage and priced accordingly. this piece may not be vintage, I suspect it's not because of the way it fits and the condition that it's in. still, it was never worn and it was expensive when I bought it so priced accordingly
