Long evening prom dress by Anoushka size 8

Anoushka elegant Red long dress, one shoulder with long sash that flows from shoulder down back and pleated across the waist with smaller drape, fully lined. Looks amazing on size on label is 10 but now a SIZE 8 as taken in professionally at side as shown in photo, but could be taken out to size 10, side zip and rubber banding on inside of dress which holds it in place at the top. The dress hangs beautifully on and accentuates the figure cost over £250 when purchased, just hanging in wardrobe and probably not going to wear again, so hoping someone else can look good in the dress. Please ask for more details if needed.
