I thought that clothes already block UV rays by being optically opaque!

A cotton t-shirt has a SPF of about 6. It will help, but we can do better, even without melanin-infused clothing.

There are also UV transparent bikinis, for tanning without tan lines or nudity.

Maybe a little. Hold a shirt up to your face and you'll still see light.
