This [[http://www.tedbaker.com/women%27s/women%27s_clothing/dresses/list.aspx#colours=13&page=1&pricefrom=99&priceto=229 one]] I'm a size 12 with a slim figure, a high, round bottom and 5 ft 7 but I AM nearly 40 and I don't want to look like mutton. If you think this will look dodgy, please link me to a suitable dress for a very important party. Help!
