If you always wear black at parties, it can be difficult to suddenly branch out into brights or sequins. So take it easy and slowly wean yourself off with similar dark colours. Navy has all the benefits of black (it's universally flattering for all skintones, it gives a sleek silhouette and it never goes out of fashion) but it's slightly less predictable. The good news is the 'don't mix navy and black' rule has gone out of the window this season and it's actually quite a chic thing to do. All these dresses would look fab with some spotty or lacy black tights if you can't bear to go bare-legged in the cold weather.
