Family wedding in Tuscany in September so will be quite warm. I am 5'6, size 14-16, quite curvy but decent legs. I love this: www.coast-stores.com/lahna-dress/dresses/coast/fcp-product/2224819698 but have no idea if it will suit me. Budget is up to £150 if I love it and can wear it lots again but would ideally spend £100 or less. Can any of you clever people help with some ideas?
