There are situations and cultures were a travel skirt or dress seems more appropriate and so I always take one plus a sarong. Also, when you go out for the evening it looks dressier. Sometimes I want to go out dancing. I definitely wanted to find some that I would wear more than once.
I take skirts with me on my trips, but some of them never got used more than once on a two week vacation.
That is just not enough wear to justify the space in the suitcase, so think about your planned activities.
On other trips I wear a skirt many times, and I am glad that I packed one or two.
I love skirts but I need to wear my walking shoes most of the time, so I get more wear out of slacks on most trips.
I have sandals and sliders for those times when I really want to look nice and wear a dress or a skirt.
Maxi or midi will work with a flat shoe also.
Here is what I came up with. Hope it helps you when choosing your travel clothes.
A separate garment is better than a dress because it can be worn more ways and you can dress it up for an evening out. It can even look like a dress if you wear it with a matching top.
If you like you can easily make your own travel skirt as it is very simple to sew one. There are lots of simple patterns to purchase or you could even make your own pattern.
If you are not interested in sewing a skirt places like Travel Smith have great looking skirts for travel.
