William and Kate always look good together—they’ve still got that newlywed glow—but recently, they stepped out looking a little too good together.

The two wore matchy-matchy ensembles as they strolled through a park in Edinburgh, both decked out in sneakers, long pants, and purple sweaters layered over collared shirts. Is it possible this was by accident? Or did they actually decide, while they were getting dressed, to match? That’s the kind of thing that may seem sweet (or not) when you’re actually in the relationship—that they longer you’re together, the more alike you start to look—but to everyone else is way too cutesy. Occasionally, it’s totally fine for pairs to strategically complement each other with their outfits. Here are some more coordinated celebrity twosomes, from best to worst:

We love that Nicole Richie‘s hubby Joel Madden chose to a tie that perfectly complimented his wife’s gold-hued outfit. The old-fashioned Prom date coordination.

Katie Holmes and Tom Cruise looked like a sweet twosome when they both wore leather jackets out in L.A. The different shades of the jackets and differing outfits underneath kept them from going overboard.

John Krasinski and Emily Blunt both wore jeans, gray sweaters, and blazers at an event, but this picture is so freakin’ adorable that it’s hard to criticize.

Ellen Pompeo and Chris Ivery should have followed Tom and Kate’s lead and changed up their outfits if they were going to choose matching leather jackets. Instead, both wore similar jeans and white tops.

Mariah Carey and Nick Cannon just welcomed twins to their family, and based on their wardrobe track record, you can bet the couple will be dressing the baby boys up in many matching costumes.

Justin Timberlake recently said that he wishes he could undo this famous red carpet moment, when he and then-girlfriend Britney Spears showed up to the VMAs in full-on denim get-ups. Sorry, JT, no can do—this Canadian tuxedo’s on the internet for life!
