PN+1 is the correct number of shirts
PBut for real, just buy slowly. Some of us here have had an addiction interest in fashion for many years so asking how many shirts is not the best question. I’d say maybe start off with a white and blue OCBD, a couple good tees, and a fun shirt for going out
SHave as many as you feel comfortable with. I probably have like 10 short sleeve button downs and 6 long sleeve button down casual shirts. Around 5-6 overshirts and 40 tees lol
Tumm
Eim not buying rn but i would buy to fill in colors i would like to see
Ei have double blue camp collars so my third camp collar is "as long as it's not fucking blue"
Ei have a light flannel and dark flannel and im 99% sure i don't need another flannel for the foreseeable future
Emy tees #s are. regretable. 
AWay, way too many. But in recent times I've been trying to implement a "one in, one out" approach.
Athrifting makes this approach pretty doable, too
