This is the first question you should ask before you start planning a travel wardrobe. If you are traveling on business, consider taking mix and match pieces. A simple skirt or pants suit, a second bottom, two to four blouses or tops and a cardigan can make up a number of professional and practical outfits, particularly with few lightweight scarves to change things up a bit. A similar concept can be used for casual travel. Backpackers often get by with as little as a pair of zip-off pants, a travel skirt and two to three thin and easily washable tops.
The best travel fabrics are light, comfortable and pack well without wrinkling. Wool is a surprisingly good choice for professional attire, but you might also consider Tencel, microfiber or other wrinkle-resistant synthetics. Cottons are more forgiving for casual wear and are typically breathable and comfortable. You also may already own suitable pieces. If you are aiming to pack ultralight, you may need to invest a bit more in modern, high-tech quick-drying fabrics to allow you to wash something before bed and wear it in the morning.
If you are planning your travel wardrobe on a budget, you can choose where to spend and where to save. Consider taking clothing you already own, even if it means a few minutes with a hotel room iron or one more outfit in the suitcase to save. Where should you splurge? Socks, underwear and shoes are good places to invest your travel wardrobe spending. Look for good quality, quick-drying lightweight socks. Choose breathable fibers for underwear, especially if you are heading to a tropical climate. You may even want to consider anti-microbial fabrics for your travel underwear. Shoes should be comfortable, well cushioned, and hold up to a lot of walking. Be sure to take the time to break in new shoes before you travel with them.
