Girls, What size upper lats do you think are best on a man?

I have started lifting weights recently. Bodybuilders tend to overdo it and get too big. I prefer to find a stopping point where it would be most appealing to women. I was wondering, how big of upper lats do you prefer? If you're not sure what that is, here it is circled in yellow:

If you could provide a picture of a man with good ones, that would be even better. Please don't show someone famous as that could lead to bias.
