I've overdone it and been too warm but I thrive in the warm stuff so that's just unpleasant and a lot of stuff to wash. And I've done rides where I never could get my core temperature up enough to ride hard enough for sustainable warmth. The resulting ride was condtioning-wise, a waste of time and a couple of times, scary. Fortunately those were on warming days.
Edit: I'm built like an air conditioner, all surface area, little volume. I've always run cold. 98.6 and what's going on? That's almost fever for me. (A little exaggeration but over the many COVID skin tests, I was only once or twice up to "par".
