Paris Hilton Talks About Sister Nicky Hilton's Possible Bridesmaid Dresses

With a Hilton wedding in the works, Paris Hilton is excited to see what her little sister Nicky Hilton has in mind for bridesmaid dresses. Seeing as Nicky is a fashion designer and has great taste, Paris isn't too worried about what her choice will be.

"It's her day, so whatever she wants me to wear, I will," Paris told People at Nicky's 365 Style book party Tuesday night, Oct. 21. "But I know that Nicky had impeccable taste, so the bridesmaid dresses are going to be beautiful."

Nicky got engaged in August to longtime boyfriend James Rothschild, but she hasn't done much wedding planning just yet. She does, however, have a gorgeous engagement ring, which she loves to show off.

"The carat size looks between 6 and 8 carats, and the shape looks square, which could be a Royal Asscher Cut," Eshed Diamonds worker Kathryn Clark told E! News about Nicky's killer diamond when she first got engaged.

While promoting her new fashion book, Nicky revealed that even though they haven't started the wedding plans, her fiance wants to be included in some of the decisions.

"We haven't started yet! We're about to. I think [James] definitely wants to have input, but I think he'll let me and my mom figure it out," Nicky told People at her book party in Beverly Hills.

The 31-year-old designer revealed that she has been focusing on her career recently, launching a clothing collaboration called Nicky Hilton for eLUXE-plus in addition to her new book, which focuses on her fashion philosophy.

So what's her main philosophy?

"There [are] three main occasions that women dress for in their life and everyone's threes are different. Mine are day casual, business and special events, and I pretty much wear six staples, five accessories. If you stick to that road map each season, you'll have a wardrobe full of things you're going to actually wear," she revealed to the publication.
