OK, I’m jumping in here to offer a suggestion based on my own experience—buy an Eileen Fisher pant.
I’m not suggesting you embrace the whole EF aesthetic, but a pair of slim, ankle-length, crepe EF pants might be a lifesaver at this particular moment of your life. When, and if, you manage to locate your elusive perfect pant, that EF pant will be perfectly happy to become your go-to travel pant—packs easily, washes like a dream, and goes with everything. And, as a bonus for Canadian shoppers, the EF pant fits a myriad of shapes so it’s easy to order online as long as you size down.

Finding those slim black EF pants added the professional edge I needed when my changing mid-section made finding a decent tailored pant seem like an impossible goal.
Oh, and EF also makes a very nice pull-on pencil skirt and an equally nice slim silk pant for dressier occasions...
