Hmmm, I haven't fully unpacked yet, but here's what I remember:
I'm in Ohio, for reference, but I have a tendency not to rotate coats as much as some. I do really need a trench... one of these days I'll get lucky!
Heavy:
LL Bean down-lined heavy coat, probably 12-13 years old and still fits - bought for me sized big and they run big, so yeah. Great to ski in, over ski pants. This jacket is overkill, even for an Ohio winter - maybe it would see more wear in Minnesota or upstate New York, but here I only break it out a couple of times a year.
Hickey Freeman charcoal overcoat, from maybe the 60's? Sucker is HEAVY. Need to get the sleeves dropped on it a bit and maybe lose 15 pounds
Mid-weight:
Cardinal of Canada (I know, I know, made in China now, but it really is decent and it was only $120 at Nordstrom Rack) black overcoat
Brown lambskin leather jacket, Roundtree & Yorke (Dillards house brand)- better quality than one would think, great leather, was only $99

Brooks Brothers navy spring/fall "Hybrid Jacket" from last winter(?) with all sorts of pockets, plaid lining, still new never worn with tags since I thrifted it as it was warming up outside. Hopefully I've lost enough weight to wear this one soon, but we'll see!
Deprecated, but I still have it for yard work: Gap black wool zip jacket with worn-out inside lining.
Light jackets:
Brooks Brothers light jacket, almost like a windbreaker, can't be newer than mid-90's judging from the label. Fits great, except the sleeves are a tad short, so I'm hoping to find a replacement someday, but that's easier said than done!
