Nicky Hilton doesn’t get to choose her own outfit for big sis Paris Hilton’s upcoming LA nuptials. “I think she has a vision,” Nicky tells Alexa, adding that she finds identical bridesmaids dresses “dated.”

Still, she insists that Paris is a “chill” bride-to-be and is busy planning her sister’s Las Vegas bachelorette party. “Vegas is always a good idea,” notes Nicky, who just had her second baby girl, Teddy, five months ago and designed a new line of “Mommy + Me” clothing with Tolani. “I think children have such a small window to dress like children, so I really don’t like when I see children in grown-up clothes,” she says. “Like leather jackets or leather pants. It’s a bit much.” But her older daughter, Lily-Grace, already has her own style code. “Her favorite shoes are these little pink Vans with unicorn horns that she insists on wearing with everything.” We approve.
