The purpose of sunscreen is to protect you from UV light, which you can't see. For example, sunblock is relatively impervious to UV, but completely transparent to regular light. So the visibility test isn't necessarily too meaningful.
I sunburn easily too, but I don't think I've ever gotten sunburned through clothing- maybe if I wore more nylon type stuff, that would be a problem, but with any regular clothes, it's just never an issue.
Something else to consider is that if you use an SPF -XX sunblock, that's the rating when you put it on, but it may be mostly gone after 6 or 8 hours, but that shirt won't wear off like that.
