The problem is, you can’t really go on holiday without one. Well, you can, but it’ll be stressy. Transferring globs of SPF30 on to your favourite dress is less than ideal, as is the makeshift sarong fashioned out of a beach towel that falls off en route to the ladies. It’s sad, this compunction to shroud your body with a cover-up — especially on holiday, a time when you should be wild and free. Last week, I was in Cascais, shovelling hash browns and bacon on to my plate at the breakfast buffet, when I noticed all eyes were on the pert brown butt of a fellow hotel guest. She was wearing a cover-up, but a short one, her red bikini bottoms (tie-sided, for those who like detail) exposed to the room. ‘Good on you,’ I thought, lost in the rapture of her confidence. And then my youngest child loomed into view, carrying a plate of three Portuguese custard tarts, one muffin, five gherkins and a pile of capers.
