Still, the line has evolved over its three years. "Before it was a lot of sweat suits, T-shirts and tank tops, but now I'm doing more denim and tops and dresses."

Punchy prints — delicate swans, glass slippers and bright red apples — define the spring collection. An apple-covered A-line dress is topped with a black belted trench coat. Swans decorate sundresses and slim-fitting shifts. Printed halters and tanks float over tiny shorts.

Solids also make a statement in swingy T-shirt dresses, high-waisted "sailor trousers" and skinny jeans. Some of the best offerings came in black, including a knee-length dress with ruffle sleeves, a scalloped hem and a white Peter Pan collar and an airy voile top worn with wide-leg pants.

Hilton's parents took a front-row seat for the show, as did actress Jamie Pressly and Petro Zillia designer Nony Tochterman, who is set to close Fashion Week with her Thursday night show. Hilton's older sister, Paris, did not make an appearance.

Though Sunday marked Hilton's second fashion week in as many months, she's not done yet. She is set to show Nicholai in Mexico City and Moscow in the coming weeks.

The cameras are coming along, too. A crew from MySpace.com has been documenting the designer's work and plans to follow her on her international adventure for its fashion feature, "The Fit."

Still, Hilton seems humble about her international success.

"I'm excited," she said. "I've never been to Mexico City or Russia, so just for me to be able to go there is fun."
