Make sure your tiniest attendants look their best, too.

Your ring bearer and flower girl will likely look adorable in anything, but why not max out their cuteness for your big day? Trending attire for the junior stars of the show does just that, with grown-man-quality tuxes and flower-themed skirt drama.

Ring Bearers

Ring-bearer outfits are “swinging from rustic toward more formal,” says Jason Rodgers, director of formalwear for Jos. A. Bank, which has matching child sizes for every suit and tuxedo.

“I know it's not a T-shirt and shorts, but if it's fit correctly, it's not going to be uncomfortable,” Rodgers says, recommending that your ring bearer get a second fitting about a month before the wedding in case he's outgrown any of his initial measurements.

Rodgers also suggests that the ring bearer match the groom's garments as closely as possible for that extra “aww” factor. Wedding colors can show in his pocket square or necktie (clip-on, of course).

Want to add some levity to the serious aesthetic of a toddler in a tux? Go for the secret-agent look—have him wear a badge, sunglasses and ear piece and carry the rings in a mini briefcase.

Flower Girls

Dresses adorned with artisanal flowers are putting the “flower” back in “flower girl,” says Lori Conley, divisional merchandise manager for bridal and flower girl attire at David's Bridal. “So many brides are honing in on this vintage, romantic feeling, and flowers are such an important part of that,” she says.

One popular flower-focused style is 3-D petals worked into the hemline, like the one by Peanut Butter Collection at Joan's Bridal Couture in Reynoldsburg, says store owner Joan Madison.

Lace and sequin details also are trending, but “little girls are more sensitive to beading and sequin placement, so watch where the embellishments are placed,” Conley says, adding that flower-girl dresses should always have straps.

And whereas flower girls traditionally have worn white or ivory to match the bride, “we're now seeing dresses with a pop of color so she matches the bridesmaids, too,” Madison says. She suggests focusing the color in the bodice or a sash.

One of the newest options at David's Bridal is a top with three-quarter-length sleeves and a separate tulle skirt, Conley says.

“Separates are huge in bridal, so it's a really fashion-forward take,” she says. “And I think tulle is a forever staple for flower girls; it has that grandeur and playfulness.”
