Casual clothing -- You will want to take some casual clothing for the daytime. This will include jeans, cords, turtlenecks, and sweaters.
Dress in layers -- If you dress in layers, you can add or subtract layers as the weather dictates.
Outerwear -- You probably will not need a heavy down coat if you dress in layers, however, you will need a jacket.
Dinner wear -- You will want to dress up for dinner each night. If you stick to a core wardrobe color, you can mix and match. Use bold accessories such as pins, necklaces, and scarves to change up the look.
Shoes -- Try to plan your wardrobe around one basic color so that your shoes will match everything. Of course, dinner shoes will be different from every-day shoes.
Misc -- Remember to take your camera and binoculars. Don
