题目：
Michelle Obama made a daring decision to return to the same designer who created her Inaugural（就职）Ball dress four years ago --- and the risk paid off.
The First Lady looked extremely attractive in a red dress by designer Jason Wu. She teamed the dramatic dress with heels by Jimmy Choo and a diamond ring by Kimberly McDonald.
She surprised the fashion world by returning to a Wu design which had been made for her.
Four years ago at her first Inauguration Ball, Michelle shone in a white, one-shouldered floor-length dress by the designer.
Wu, who was 26 at the time and had only been working in fashion for three years, saw his career take off after the First Lady’s surprise decision to wear one of his dresses.
He said at the time that he was unaware she had chosen the dress and had been watching at home on his couch and eating pizza when she appeared.
After her 2013 decision, Wu told Women’s Wear Daily: “Mrs. Obama likes to keep her secrets. She fooled me again.”
Wu released a women’s clothing and accessories（配饰）collection at Target last year and continues to be popular with the First Lady for official appointments.
The sleeveless dress with low-cut back flattered （突出）49-year-old Michelle’s arms and neat waist.
It had been created especially for her by Wu and was a departure from the dark and plain color tone she stuck to at earlier inauguration events.
Vice-President Joe Biden’s wife Jill also looked attractive in a blue silk dress by Vera Wang at the Inauguration Ball.
