Maya, I bought and returned a different style J Crew coat in the poppy color last winter (ultimately kept navy). IRL, I did not like the color at all - way too orange for my skintone. It may suit you better but I like more blue-reds and this is a warmer orange red. FYI.
I haven't read through all the replies but in this transitional weather, I wear my non-leather moto jacket quite often. Mine is from Hanna Andersson and is quite old - maybe from 2004 or 2005?? Anyway, it's the same one I wore to the meet-up back in March. I'm not sure what the material is - a very heavy duty nylon of some kind?? Anyway, it's super windproof and has a nice felted interior. I can zip it up over a lightweight sweater, add a scarf and I'm set for 50 degree weather. I wear it with both pants and skirts. Any colder and I switch to a wool jacket - short or long. When it's 35 or colder, I've been wearing the puffer. I also have a quilted jacket that looks a little grandma but works well for the in-between weather too.
You definitely need a variety in this type of climate!!
BTW, I have a leather (real & vintage from MIL) trench and it's not warm at all!
