There may be new trends aplenty at New York Fashion Week, but Michelle Obama is returning to her signature style.

Today on the White House's South Lawn, the President and Mrs. O hosted, among others, judo competitors and fencing champions to support Chicago's bid for the 2016 Olympics.

Dressed in a teal cardigan, yellow layering tee and printed floral skirt, the First Lady brought back the belted-over look with a Sacai cincher. She also donned her favorite green Jimmy Choo "Glacier" kitten heels for taking in the sporting festivities.

At one point, a playful Mrs. O got caught up in the excitement and goofed around with a fencing sword (aka épée). President Obama better watch out -- she's a fierce First Lady!

It may be fall, but you can still read up on Mrs. O's summer fashion choices here.
