Definitely merino for baselayers, especially if you'll be mixing outdoor and metro travel. Icebreaker stuff looks a little more techy, while Ibex has a lot of nice casual styles that don't look at all like sportswear. Definitely look at the "Villa" dress from Icebreaker, though. It is an indispensable travel piece. Add some leggings and a scarf and you're good for long flights, short hikes, dinner and dancing, whatever.
For pants, look at Rab, Prana, and Kuhl. A lot of "travel" brands (Royal Robbins, Ex Officio, etc.) just make you look glaringly like a tourist (cargo pockets and khaki!).
For a hardshell, I'm pretty in love with the Westcomb Fuse. Took it on a very rainy 3-week trip in the southern Appalachians this summer and was blown away by the breathability and durability. Performed great on snowshoe trips this winter and spring, too. Also, very flattering fit; looks more like a nicely tailored softshell than raingear. The pricetag on Westcomb is a killer, but keep an eye out for clearance and samples. I've become a convert to 3-layer shells rather than 2-layer (aka 2.5-layer), because the increase in comfort and durability is noticeable. I find that eVent and Neoshell are breathable enough to double as windshirt and rainshell–but I run cold and don't sweat heavily most conditions.
I actually find that men's shoes fit me better about 85% of the time, especially in running shoes, but my feet have widened substantially due to the amount of time I spend barefoot. (May also be genetic; my mom wears between a 2-E and 4-E width.) I've also found that bringing a pair of light sandals or canvas flats vastly improves my travel experience. It's soo nice to change out of the sweaty mud-covered hiking shoes into something clean and breathable when you're at a hostel, restaurant, museum, etc.
As your GF probably knows, shoes and pants rarely fit when ordered online and should be tried on in-person before purchasing ;)
