Please can you wise ladies help. I am panicking over my choice of dress for my partner's Christmas do (Saturday) I have just re read the invitation and it states black tie and cocktail dress. It took me ages to find something I feel comfortable in but I am now thinking that a cocktail dress should be short rather than full length? I planned to wear it with silver sandals and a navy chiffon cover up. Do you htink it will be ok or do I need to look for something else (I am very uncomfortable dressed up) Thanks for your help.
