Just that really. On the rare occasions I go out I never know what to wear as all my clothes are either casual or mumsy. I'd love to have just 1 gorgeous dress to throw on which makes me look great - trendy but not "mutton dressed as lamb" (I'm late 30s), flattering but not frumpy. I'm not one for heels so something that goes with trainers or boots. Any suggestions re where to look? Budget wise up to about £200. Thanks in advance!
