Slowly but surely, the overalls trend is gaining traction, proving that it is in fact, the one-piece of the season. Two months after our initial post, the number of celebrities (including one stylish baby Prince George) who have been snapped wearing the denim dungarees has tripled. And we have to confess that we’re slightly obsessed, too, dressing it up in a menswear-inspired getup or playing it down with a simple chic tee.

But with every trend, it all boils down to one important question: Does it have staying power?

All signs point to yes (though we have to admit we’re slightly biased). Look to street style savant Olivia Palermo for sartorial persuasion. Inked in a dark wash, hers (Paige Sierra Overalls in Vintage Black, $279; paigeusa.com) definitely err on the side of wearability. She teamed them with a sheer black long-sleeve top, statement shades, a ladylike handbag, and embellished flats—perfect for casual hangouts and weekend strolls.
