I might wear a light jacket at 60 but I'd rather try to wear a shirt and sweater - I hate coats so I'd put that off for as long as possible! Of course wind or dampness also factors in.
i would only wear that above a heavy sweater and a long sleeve shirt, not above a tshirt, that's a bit of a weird look for me.
Generally in september / october I tend to wear cotton jackets or light soft shell jackets for cool/mild weather when going out, which can be worn above a tshirt or a long sleeve shirt / hoodie. When it gets cold around mid november I switch to something more substantial.
Let's assume a typical 30-45 minute, slow-paced, dog walk with plenty sniffing stops, when I patiently stand still:
28 F - 100 F : T-shirt + shorts
20 F - 28 F : Long-sleeve shirt + shorts
15 F - 20 F : Long-sleeve shirt + pants
0 F - 20 F : Light Jacket
-20F - 0 F : Windbreaker jacket
-40 F - -20F: Lambskin Fur Coat
Strong windchill can mean skipping a row (or two, if it's really windy) in this table.
I do, occasionally cheat, though. If it's a Blizzard out there (I love my long Blizzard walks), even though it's not cold (e.g. it's above -20 F), I still take the Lambskin Fur Coat, for safety.
I rather open up a button for few minutes, in the middle of Blizzard, to cool myself down, as it's incredibly easy to get very hot in that Coat, while wading through snow (it's quite an intense workout, actually - especially walking against the direction of Blizzard), especially if it's above -20 F.
My Husky doesn't seem to experience the same problem...

I don’t wear it over a T-shirt, I usually wear it over a fleece or sweater

And just like dogs shedding into their winter fur, we do the same .. kinda... in a different way. We acclimate to temps. So while I would need a sweatshirt at 50F in Autumn, it would need short sleeves in winter.

For instance, a recent study conducted by researchers led by Wouter D. van Marken Lichtenbelt at the NUTRIM School for Nutrition, Toxicology and Metabolism corroborated earlier findings that ten days of cold-exposure was enough to increase the body's ability to generate warmth without shivering.
The secret to the spike in heat production? According to the researchers, an increase in activity in brown adipose tissue, in parallel with an increase in nonshivering thermogenesis. Brown adipose tissue's main physiological purpose is to generate heat independently from the teeth-chattering muscle contractions that we often experience in the cold. Once thought to serve this role primarily in human infants, recent studies like this one have demonstrated that brown adipose tissue plays an important role in acclimatization to cold temperatures in adults, as well. As van Marken Lichtenbelt and his colleagues explain:

OMG ! You have no idea how happy I am see posting you something like this!!!
I call this situation a "thermostat reset". It happens to me every single winter and it doesn't even have to take 2 days, let alone 10.
Usually, with every Blizzard hike (even if it's just 3-4 hours), my internal thermostat resets, and I am literally sweating, while sitting in 60 F temperatures. It takes 2 weeks of sweating to get back to uncomfortable tolerating (with screeching teeth) 70 F again.
Thankfully, last winter, I was working from home and not in an overheated office, so I could simply keep all windows open (to the great joy of my Husky) and keep the temperature inside at a comfortable 55 F (with a constant wind from open windows).
And, it still took about a month till I could tolerate anything above 60 and I didn't even reach 70 F before winter was over. I spent at least 6 weeks at 55 F, and another 6 weeks at ~62 F indoor.
I suspect it has something to do with me, in past, going from 100 F Finish sauna (the one that properly burns and hurts when you breathe there) and jumping right away into freezing water. Something changed inside, once I started doing that regularly.
That thermal shock is an incredible chemical cocktail, just don't tell that to your cardiologist
Do you have some other info on the "cold resistance studies" ?
