So my progression for running clothes:

65+: tank top, running shorts, regular running socks

50-60ish: short sleeve shirt, shorts, regular socks 50ish: short sleeve shirt, shorts, regular socks, BUFF

The following ranges start having options I'll swap around based on other variables such as: wind, humidity, duration of run, how long I might not be moving

40-50: short sleeve or light long sleeve (usually gets rolled up at some point), shorts with compression underwear, buff, ear muffs or second buff on ears, and light running gloves

35-40: long sleeve, light weight running wind breaker shorts, midweight 3/4 leggings (think basketball or HIIT categories), buff, ear muffs or running beanie, gloves, wool running socks

Sub-35: thermal long sleeve, possibly sorry sleeve with 3/4 zip top, wind breaker, buff, beanie, gloves, wool socks, thermal leggings, shorts

Key thing is finding what works for you. I've done stairs workouts in a mixture of thermals in 35 degrees. Then some dude visiting from Montana was shirtless in running shorts. So definitely experiment.

Something to keep in mind is you're dressing for the whole run. It can be easy to over dress when you first walk out the door and on that first mile. It might be good to plan runs that go by your house/vehicle/drop spot while figuring out what layers work best for you.

But definitely look into a buff/neck gaiter. Covering the neck can make a difference. Plus they are versatile for neck to head coverings.
