SPF Clothing

The ad for one brand of SPF clothing says the following: “Omni-Shade is a revolution in sun-protective clothing. The Sun Goddess shirt with UPF 50 protection effectively blocks 98% of harmful ultraviolet radiation. So you can stay in the sun longer, without all the messy goo.”
I know that some people are borderline hysterical when it comes to sun exposure, but do we really need SPF clothing? Are we that afraid of a little tan? But even if you are terrified of exposing your skin to the sun, isn’t just a regular shirt enough?
Would you buy SPF clothing?
