I remember these signs when I was a kid in south FL in the 70s. It was popular to keep the beachgoers out, I don’t know if it was to keep the company out of hot water should something happen to the shirtless or shoeless customer while they’re in the store or whether it was just a choice in who to serve.
As for your question about pants: Since the “No shirt…” phrase isn’t there to make something legally binding but rather a notice to people that this particular business is exercising their right to not serve you, no, you likely won’t get served without pants.
