Even if you won't be traveling for a few weeks or months, you can check the average highs and lows to help you anticipate your wardrobe needs as you prepare. If you live somewhere warm and will be traveling somewhere cooler, do you need to invest in a jacket? Or vice versa—do you live somewhere cool but will be traveling to a hot destination? You may need to purchase shorts or sandals so you will be comfortable while you travel. Will you be sightseeing, lounging at the beach, going out on the town, or visiting museums? Having an idea in mind of what each day is going to look like while you are on vacation will help you plan what you are going to pack.  For example, if you are planning on staying at a remote cabin for a week, you probably don't need to bring a dressy outfit for a night out. Make a list of all planned activities and write down what kind of outfit you will need. If you are packing for a family, it's helpful to make a list for each person you're packing for so you don't forget anything. Only pack clothes that can be worn with the rest of your wardrobe. It helps to lay out outfits on your bed to make sure things go together. If you want to pack your favorite skirt but aren't bringing a top or shoes you could pair it with, you won't end up wearing the skirt, so leave it behind. Similarly, if you bring ties or dress shoes, make sure they coordinate with your shirts and pants.  If you pack a jacket or blazer, make sure it coordinates with all the shirts you are bringing. Be mindful when packing accessories, too. Pick colors and designs that will work all your outfits. Don't forget to think about the kind of footwear you will need. For hiking you will need a pair of sturdy boots. For the beach, you'll want flip-flops. If you need dress shoes for fancier events, take those into account, too.
