Light blue and nude formal/prom dress

Light blue sequins and stones with light pink and light purple accents. I never wore this dress so it is still brand new. It is a mermaid dress with an illusion neckline. It is sheer right in the middle at the stomach and at the bottom. It is more light blue than nude at the bottom as well! I have no clue what brand it is but it is very good quality and I bought if from a bridal shop!!
