Is the best, most "fashionable" way not to burn this summer to cover up?

I think Nigella Lawson took this a little bit to an extreme, don’t you think?

Correct me if I’m wrong, but I would have thought black absorbs heat even more than any other colour? I don’t think this will catch on very soon sadly, sorry Ms. Lawson! Girls, I think we’d best just stick to our usual swimwear.
