Here's what I wear to work every night during winter (I work the night shift outside in southern Idaho): athletic socks underneath thick wool socks in my winter combat boots, fleece leggings underneath lose long-johns underneath heavy cargo pants with hot-hands warmer packs in the pockets underneath outer pants made of the same crap as snow-boarding pants, a long sleeve shirt underneath my uniform under-shirt underneath a jacket liner underneath another long sleeve under-shirt underneath my uniform top underneath a thick fleece jacket underneath the military-equivalent of a snowboarding jacket, thick winter gloves, a fleece neck-sock, face mask, and fleece winter cap.
Who needs to dress you up to keep you warm? I mean I would cuddle you against my warm body and hold you close in my arm (like a teddy bear) s so that you would feel extra warm, and we could even enjoy a nice movie all at the same time?
Get some long underwear, it makes a hell of a difference and you can wear it with any clothing you would normally wear in cold weather. I have these nice thick fleece pajama bottoms and if I wear long underwear with them I am invincible to the cold. by the way a good way to stay warmer is to keep your feet warm.
That sounds kinda like me haha i've been doing the exact same routine everyday :( if you simply just want some "warmth", get a Canada goose jacket, the warmest jacket you can ever found in North America, though they are kinda expensive lol or you can look up the new advertised winter jackets in The North face and Columbia, these are more economic options :) Otherwise, you should be think of buying a car, which is more costly :)
If you really wanna stay warm goose down is the answer! I used to do some mountaineering a few years back, I can't remember all the facts but it went something like mankind hasn't come up with a better insulator- science vs millions of years of evolution. It's light weight so you can pack it down really small as well. A lot of these jackets have a DWR (durable water repellent) coating on the fabric but they're not waterproof. This can be a problem if it's wet where you are, if down looses it's "loft" it clumps together and no longer traps the air. However extreme cold and wet aren't usually associated with each other for obvious reasons.
Mountain Hardwear and Rab are probably the best makes.
I'd go with layers personally. Layer a thinner long sleeved shirt under a T shirt under a hoodie, then top it off with a jacket. If you have long johns, pop those suckers on, and wear jeans. Top it all off with a scarf and you can pull the hood up to cover your head. If you get hot, you can take off the jacket and scarf and still be warm.
Wear a long sleeve thermal shirt, and over that wear a regular long sleeve shirt, and if you want to then you can wear a flannel over that too! :) And then wear a sweatshirt and a jacket haha. That's all the layers I could think of
