The halter string top is flattering for all sizes. It shows off a lot of healthy skin and it accentuates the shoulders which adds a slimming effect on the body.
You rarely see black summer dresses out there. I found one that actually looks fresh and not heavy or severe. Something a girl can wear from day to night.
The lovely waist detailing has a Grecian touch.
Also the lace trim accentuates the lightness of the swingy fabric.
