A short or a long trip, one needs to be at their most comfortable and have a relaxed journey. How else is one going to enjoy themselves otherwise?
Traveling, however preplanned, it is never going to be fun if one is not in their comfortable outfit. One has to not only consider the destination but also their outfit while traveling. The lighter the clothes, the better it is.
It would of course depend on each woman considering their individual preferences and personality and not the least, their style quotient too. Even the age counts here. A professional would always prefer formals. But, for a teenager, it would be just the casual outfits like jeans and simple t-shirts.
There are certain points to be considered before deciding on the outfit. It would depend on the place and the prevailing weather where one is likely to visit. If it is hot and dry, it has to be light clothing or if it is cold, then one would need to be ready with woolen clothing. Pure cotton goes along well with any of these climates; but gets wrinkled through the journey. It should not be so light colored that it gets visibly dirty. Big prints would be a better option.
Women are usually not just happy with their clothing. The accessories too are equally important to them. If it is a hot place, then a crushable hat, or woolen gloves and socks for a cold place should be added to the list. And do not forget your scarves and sunglasses.
