We’d like to thank the sprinklers at the playground for our kids’ requiring more costume changes than Anne Hathaway at the Oscars.

Because if it weren’t for their multiple summertime wardrobe malfunctions, we’d never have discovered the easy-breezy outfits from new Spanish fashion line Nadadelazos.

With staples (think tanks and sundresses) plus of-the-moment looks (like blousy rompers and sarouel pants) the line reads stylishly carefree even when you do the old switcheroo on a park bench.

The all-cotton pieces showcase original prints — a dash of Euro mixed with the best of the ’70s, a combo we find hard to resist — by designer Tina Laux. And they’re no worse for the wear after being rolled up in your diaper bag awaiting their entrance.

Cue the ice cream truck — you’re ready.

Available at Sweet William, 85 Kenmare Street, between Cleveland Place and Mulberry Street (212-343-7301); 112 North 6th Street, at Berry Street, Williamsburg (718-218-6946 or sweetwilliamltd.com), $38-$48.
