Speaking to PEOPLE last October, Simpson said that she will be passing on some of her stylish staples to her daughters.

"There are some amazing vintage pieces I am keeping for Maxwell and Birdie," she said in a behind-the-scenes look at her latest collection, adding, "I also have some special pieces of jewelry that will be theirs when the time is right."

She continued, "Maxwell has already grown out of my shoe size, so sadly she never got to wear the Jimmy Choos. I didn't expect that or I would have turned my storage into her closet!"
