Holiday formal wear doesn’t have to be a one-hit wonder. Give this season’s standout styles a serious shakeup, to make them hip, happening and playground-friendly.

OK, so maybe you spent a little bit more than you should have for the kids' Easter outfits this year. But seriously, how could you resist? The pretty floral dress is picture-perfect and in that classic seersucker blazer and matching pants, well, he's a dead ringer for his dad. Adorable? Yes, but one wear, and now they're sitting in the cedar closet, waiting to be handed down to your younger ones.

Well, take them out from hiding: With just a tweak here and there, you can instantly transform the don't-mess-me-up formal look to made-for-play hip. Make the prim-and-proper dress mini-fashionista by throwing on a jean jacket (push up the sleeves, of course) and swapping pink sandals for hippie-chic Birkenstocks. For him, separate the buttoned-up seersucker suit and he'll instantly channel cool-dude: That everyday polo and worn-in cargo shorts uniform gets a shot of guy-style when topped off with the blazer (you thought he'd never wear it ever, right?); the pants get mod with a red polo peeking out from a wry t-shirt and his beloved flip-flops. Too cool for school? You decide.
