WORN TWICE Theory Treeca Full Length Pant in navy, stretch wool I wore these twice (with the matching jacket I'm also selling) and they tragically don't fit me anymore. The wool is stretchy, breathable, and very comfortable. Below is the blurb from Theory because they're more eloquent than I am: A distinguished Theory favorite, this full-length pant is tailored in our best-selling Treeca fit, which flatters the leg with a slim-cut profile. It’s detailed with a hook-and-zip closure, side slip pockets, and a back welt pocket.
