Calvin Klein sleeveless floral formal gown

Only worn ONCE! As pictured in photo 2 I only wore this one time for my sister's white coat ceremony for her medical school. It is a purple floral, high-low, mermaid style gown. This is sleeveless but the straps are thick, as is the dress material. It's not the best for summer weather, more of a fall or winter fabric. I dropped weight and now this doesn't fit. Has been cleaned and stored in a smoke free home.
