Formal gown - vintage

This was my daughter’s prom dress in 2013. It has been stored in a dress bag in my closet since, so definitely vintage. The tag says size 6, but pretty sure the dress was altered to a size 2, please see measurements below. I am unsure if the alterations can be taken out, but I don’t think my seamstress would have removed material from the torso, only the bottom. My daughter is 5’3” and I have included some photos of her in the dress, she did wear a 2” heel. The dress was bought new from a local bridal shop and was $500 at the time of purchase. Only worn once. Official color was neon coral. I do not see any flaws, all beading and rhinestones are in tack. Casssandra Stone by Mac Duggal. It does have padded cups, side sash, and front leg slit. Please message for more information or photos.
