Peter Som plays with olive green, navy in wide stripes and bold florals

NEW YORK, N.Y. - Peter Som, a favourite of first lady Michelle Obama, ramped up the fun Friday, with olive green in broad stripes and bold florals on his New York Fashion Week runway.

Som transitioned from easy living dresses, flouncy short skirts and sturdy jackets and coats for day to a series of gold lame looks for evening, offering a youthful flourish with flowery appliques on numerous outfits.

Fourteen-year-old Willow Shields, who plays Primrose Everdeen in the "Hunger Games" movies, counted the three-dimensional applique among her favourite things from Som as she attended her first-ever fashion show — in grown-up heels!

"I'm getting better in heels, but they still hurt," she laughed.

She spoke like a pro about the black Som outfit she wore, explaining how she likes the way the designer "mixes different things," like leather and the sewn-on flowers.

"That gives it a bit of a grungy look, but then there's flowers and that gives it a girly look. Balancing that is fun," she smiled.

The playful mood of the collection continued with colorful aprons wrapped around floral-print shirtdresses, a sleeveless top in with a fluttery, oversized back ruffle, and roomy T-shirts in snake prints in light pink and white.

Som turned to Christian Louboutin and his signature red soles for comfortable leather flat sandals in white, black and silver.

While Shields appreciates Som's "mixed up things," she said her heart remains in thrift shops and vintage stores. She said they're easier to find in her part-time hometown outside of Albuquerque, New Mexico, than in Los Angeles, where she spends most of her time now.

Anything in particular she likes to wear in her down time?

"I'm not stuck on one thing," Shields said. "One day I'll wear a pair of leather pants and a blouse and then one day I'm going to be wearing a corseted dress from the '80s."
