I've owned my black BR trench for years. It is unlined, and water resistant not repellant, but it is a great trench because it is very lightweight so I can easily take it on all my travels - takes up very little space. It even fit easily in my tote in Paris - so I had it with me on those days when it would suddenly start to rain.
But, I bought it long before YLF and when I began finally wearing jeans. So it worked well over khakis or black & white tweed trousers or grey trousers. I would be sure to wear a top that had a bright pop of color for interest.
I don't know if a non-black trench is in my future. Let's just say, it's not very high on my shopping list right now: it seems in Boston we have extreme weather now - it's either too cold for a trench, or too hot.
Also, most trench coats look horrible on me! I don't like ties on my coats, for one thing. But the bigger issue is that most classic trenches seem to have too much goo-gah going on on the shoulders, and then there's often that weird back vent. I think I end up looking like a linebacker and a hunchback.
Did you check bluefly.com? I recently posted a link there - they had a wide array of cream trench coats.
Oh - and I guess I'm still kicking myself because Ann Taylor last spring was selling the most GORGEOUS red trench.... I tried it on and it fit and flattered... it was the perfect shade of red for me (with blue undertones)... but I hesitated and it quickly sold out.
