Washing your clothes while travelling is something you'll have to do if you're travelling for more than a week. And even if you're travelling for a week, you can pack lighter if you're prepared to do a little bit of washing along the way.
The most important thing to remember when travelling is to pack light. This means you need to take fewer clothes, but you should also consider what each item weighs, and how easy it will be to wash - and of course, since you will have fewer clothes with you, you'll need to wash what you do have more often.
Avoid very heavy things like jeans and bulky jumpers, as they are hard to wash and even harder to dry. Leave the big towel at home and pack a sports or travel towel, which takes up a fraction of the space and dries quickly.
If you're going somewhere cold, the trick is layering. Pack lightweight trousers and thermal underwear to put under them. Instead of one thick jumper, pack three thin ones - it'll weigh the same or less, you can rearrange them for a change of wardrobe, and they'll dry so much faster when you wash them.
