Packing for any trip can be difficult, you never know what you will end up needing so you try to plan your wardrobe around the “just in case” aspect. When you are only going out of town for a few days, it is easier to determine what you should bring and what “just in case” scenarios are unlikely. If you are planning an extended stay trip, you will have more “just in case” moments, and adding those up can be overwhelming.
Depending on how long your stay will be, you may want to check your baggage so you can bring more with you. If you are worried about your baggage being lost, you can put two or three outfits in a carry-on bag, while still keeping the majority of your luggage in a checked bag.
Pick one basic neutral color for your bottoms, like black or brown, and stick with it for all bottoms you choose to pack. This will allow you to match your tops to any bottoms with ease. You also will not have to bring as many pairs of shoes to match. Take three or four bottoms for business, jeans, and something comfortable. If you have to wear blazers or suit jackets, match them to your bottom color scheme to keep things simple. Coordinate your ties with this color scheme too.
For your shirts, you can now go with any color scheme you want, since everything else is a basic color.
Bring a maximum of three pairs of shoes. A pair of sneakers and two pairs of business shoes. One pair of heels, flats, and boots is a good way to select your shoes. Wear the heavier shoes on your travel day so you have a little more room in your suitcase; it will also help if your airline charges your baggage by weight.
If the need arises for a new outfit, you can always buy one on your trip instead of overloading your suitcase for every contingency.
If you plan to check your bag, you can pack your bigger bottles of shampoo, conditions, body wash, toothbrush, toothpaste, and other hair and body products you need. Make sure you put everything in resealable plastic bags so nothing will leak on your clothes.
If you are doing a carry-on bag, keep in mind that liquids and gels cannot be bigger than three ounces, and they have to be packed in quart-sized plastic bags that will need to be easily accessible when you have to go through airport security checkpoints. Since you are doing an extended trip, it may be better if you buy larger bottles of your toiletries when you reach your destination. You can also ship your toiletries, if you really want to travel with a carry-on. If you love having tons of hair and skin care products, cosmetics, and perfumes, this might be the way to go. You will not have to worry about suitcase space this way, and you can have all of your products with you; buying all of those at your destination can be much more expensive than shipping.
You will definitely need to bring your laptop with you, and make sure you have the thumb drives and cords you need. A portable surge protector for your computer cords is another good thing to pack.
Your phone is an obvious electronic, but make sure you also have your charger packed. Those are often forgotten by travelers. A car charger is also a good idea if you plan to do a lot of driving. A portable charger is another good thing to pack, so you can keep your phone charged while you travel.
