Clothes! You have to wear some.

You can avoid ignoring it into your checklist. Below are some of good advises for your clothes:

• Packing tips to avoid wrinkles and save space - roll clothes up and stuff them into a bag like cigarettes are packed into a cigarette box
• Pack a change of clothes for every 3 days of the trip (up to a maximum of 3 changes), and do laundry in the hotel sink.
• Tuck your accessories in plastic bags into your shoes, filling up what would just be wasted space.
• Use zip-top plastic bags for T-shirts, socks and undergarments, others for technical accessories such as cords and batteries and others for toiletries and stationery
• Choose a neutral colours black and white, maybe blue and tan, then everything will match. Pack colourful scarves and other accessories. Use layers to add variety.
• Choose your favourite clothes not new ones and you will feel better when you wear them day after day.
• Jersey type fabrics, as well as washable and easy-dry cotton-blends and athletic type fabrics, usually pack flat, don't take up much space and travel well. Polyester-wool-and-Lycra blend type of material, cotton and polyester /cotton are best.
• Avoid jeans because they are too bulky, can't effectively be washed in the sink and take too long to dry. It you must take them, then wear them onto the plane.
• Use layers for cool weather and variety. The only coat you take should be worn onto the plane. Take short-sleeve tops, long sleeve tops, a light cardigan, and a scarf to create variety.
• Wear the bulky stuff onto the plane, including heavy jackets, woollen items, scarves and walking boots. You can take them off in the plane and they don't count as luggage.
• When you are packing, it is a good idea to make two piles before you put things in your suitcase - 'Must haves', and 'Nice to haves'. Pack the 'Must haves', first!
• Roll up T-shirts, underwear and everything else as well – it may seem odd, but things don't get wrinkled this way and they pack so much tighter.
• Compression and vacuum bags can help to squish more stuff into a bag. These types of bags are very useful when you are returning home, when you are less concerned about wrinkled clothes and may want more space for souvenirs.
• Choose clothes, especially shirts and underwear that you can wash and DRY yourself - take laundry soap. Fast-dry clothes may not be the most stylish for the fashion-conscious, but it is generally lightweight, washable in a hotel room sink and takes up little room. Wash and dry when you can.
• A thermal T-shirt and also long underwear is less bulky than a jacket will allow you stay warm with a sweater and woollen jumper even in below freezing temperatures. You can layer these items for varying temperatures.
• Jettison stuff constantly: books etc. Bring old underwear and discard along the way. You can use the space that is left for your purchases and souvenirs.
• Preventing wrinkles: For women its rayon or polyester; For Men, its no-iron shirts. You can Use steam from the shower to remove wrinkles.
