'Say Yes To The Dress: Big Bliss' Bride Tries To Top Her Sister's Wedding Dress

Most brides just want to find "the one" when it comes to wedding dresses.

But for "Say Yes To The Dress: Big Bliss" bride Linda Fillippi, one-upping her sister seems more important than finding the perfect gown for her Big Day.

In this clip from "Big Bliss," the plus-sized bride explains why she feels the need to compete: "People still talk about her wedding, and it's almost two years later," says Fillippi. "So we just need to top that."

Even when Fillippi finds a wedding dress that she likes, it seems to fall short of her sister's. "This one is like hers but toned down more, and I don't want that," Fillippi tells the Kleinfeld Bridal associate. "I already told her about the need to top her."

See what happens next on "Say Yes To The Dress: Big Bliss" Friday, Nov. 25 at 9 pm EST on TLC.
