ABC News' Bianna Golodryga and Mary Pflum report:
For years, an ever-growing number of celebrities have decked out their little girls in runway-ready fashions.
But move over, Suri Cruise, because little boys are now getting in on the act. Take Rachel Zoe's son, Skyler, and Gwen Stefani's sons, Kingston and Zuma.
"We're seeing little boys doing jewelry," Michelle Madhok, the editor of MomFinds, a fashion blog devoted to the latest from celebrity babies, told "Good Morning America." "We're seeing them do more and more of the current trends, like color-blocking."
Among the most fashion-forward boys these days is Kourtney Kardashian's son, Mason. Fashion icon Victoria Beckham's three sons, Brooklyn, Romeo and Cruz, are also making their own statements with their clothing.
Zoe's son is just over a year old, but he already has a closet filled with accessories. While shopping with his mother recently, Skyler was spotted wearing a Missoni scarf.
He has also been seen sporting little-boy bling, a necklace that doubles as teething beads.
Leslie Venoku, co-founder of Big City Moms, one of the nation's largest support groups for new parents, told "GMA" that she has seen a steady uptick in mothers' dressing their young boys in high fashion and jewelry.
"When we first started doing our events, babies were babies," she said. "They wore like the little velour outfits, the onesies. Now we're seeing, you know, babies 1 week old wearing sneakers and hats and the sunglasses. That comes pretty quickly."
"GMA" assembled a group of mothers to talk about the trend. They told us that they love to dress their little boys in the latest fashion trends, which include skinny jeans, skinny ties and sunglasses.
Elyssa Katz, whose son, Noah, is 8 months old, said Fedora hats are "staples" of her son's wardrobe. She said she loves the accessory on her son so much that she buys the hats in bulk from Baby Gap.
The mothers admitted that their obsession with fashion for their little men could stem from their not having daughters.
"When I first found out I was having a boy, I cried," Katz said. "I said 'But there's nothing for him to wear,'" she recalled. "But then when I got a grip, I found out there were a lot of things out there and I realized, 'Oh, It's so cute. You can give him a little personality.'"
Now that they've discovered how to accessorize their sons, they say there's no turning back.
"You know, why should girls have all the fun?" Melissa Fluer said. "It's, you know, I have two boys. Great. You know, this is what I was dealt with and I might as well have fun dressing them while I can before they change their mind or before they tell me what they want to wear."
