Think the whole retro Palm Beach look is over? Well, yes and no.

It used to be that trends were on a once-a-decade cycle. Now they’re on a once-every-couple-of-months cycle. Which is to say a look can be hot in March, over in May, and back today.

This time around it’s the Bernardo Miami thong, a true classic from the old school. The leather flip-flops are made the way they always were: by hand, and in a mouthwatering array of colors. Spirituali on Larchmont, which can barely keep them in stock, sells a nice selection — though you should arrive prepared to purchase more than one pair. Because once you’ve experienced the pure wearing pleasure, you won’t be able to take them off. Like wee Barcaloungers for the feet, they cradle and cushion — while looking incredibly smart.

Best of all, you can toss them in the back of your closet and pull them out just in time for vacation in December, when they’ll be coming back into style.

Try to keep up, people.

Available at Spirituali, 120 North Larchmont Boulevard, between First Street and Beverly Boulevard (323-462-4229). To see styles, go to bernardofootwear.com.
