MAKE A PLAN AND STICK TO IT!
Like an architect planning a building, so must you plan the contents of your suitcase by creating a list.
A packing list eliminates the panic of last-second packing, serves as a handy guide for repacking at the end of the trip, and can be beneficial in the unfortunate event of lost or stolen luggage.
When planning your wardrobe, consider the events you will participate in both day and night and write down a possible outfit for each activity. Crosscheck this list to determine if one piece can cover multiple occasions.
Pick clothes that coordinate well together, based around complimentary colors.
Check the weather forecast of the destination and plan
accordingly. Also, be sure to know the local traditions, where a t-shirt for dinner could be a serious blunder, or bare shoulders may bar your entrance into such places as St. Peter's Basilica in Vatican City.
For almost all outdoor activities, take pieces that can be layered.
Forget dress clothes for every occasion. The world at large has relaxed its dress code, showing almost universal leniency to tourists.
Dark colors, a black dress or blue jacket, will get you through most dinners and plays.
