During the day, you can dress in whatever you like. However, on all our ships, we have two dress codes that apply in the evenings: Evening Casual and Black Tie. Nights where the dress code is Evening Casual, you can bring out your best shirt, dress and smart, dark denim. For nights where the dress code is Black Tie, make sure to pack your best tux, suit or cocktail dress.
 

There are some venues on each ship where dress codes don’t apply, so make sure to check your Horizon paper that’s delivered to your cabin each day to check where these are, as they vary ship by ship. For those travelling on family-friendly ships, dress codes also don’t apply to children aged 12 and under.
