I recently got the LLBean travel catalogue. A friend says she wore the black travel knit slacks for the flight over and then, with nicer, maybe even dressy tops, for dinners. She was on a high end safari with time in various cities along the way -- some very nice places, I gather -- so needed something that looked very nice. She said the cotton/stretchy combo meant the knees didn't bag out and they were still comfortable. She said this was much more comfortable than jeans for traveling. It's also a fairly fine weave so it didn't look too sporty/casual. Sounds like a versatile option. I haven't gotten to the local LLBean store yet, but the catalogue lists several colors (navy and dark brown, at least) so you could pick your best color for mix and match. There are, of course, several other companies that make similar products. She said to look for at least 12% stretchy stuff.I was figuring this would look nicer than jeans, certainly for European environments where many folks are a little dressier. Now to deal with the concept of people not wearing "tennies" aka sneaker-looking shoes and finding something like black sneakers with decent support or walking shoes that I can stand (might look ok with black travel pants) to take care of walking on all those cobblestones without agony. :D (Black isn't my color but I already have a black pashmina so probably black shoes and black slacks and.... crayola color tops.)
