BIRTHDAY WISHES: A little post-show rest will have to wait for Monique Lhuillier.

After showing her spring collection at the IAC building Tuesday afternoon, the designer said she planned to celebrate her birthday two days early this year. Twenty of her friends had flown in from Los Angeles to see her runway show and they all planned to join her tonight for “a lovely dinner” at Indochine. “That’s it. We’ll catch up and share some cheers maybe.

“September is a beautiful time to be in New York. And they wanted to see what I’m always busy working on and they wanted to be here to support me.” Lhuillier said.

The designer also had such supporters as Jamie Chung, Cara Santana, Hilary Rhoda, Ireland Baldwin, Sami Gayle and Brad Goreski watching the show. Classic pianist Yundi Li was another front-row guest. The musician has caught a few fashion week shows including Dennis Basso’s earlier Tuesday, as well as the Oscar de la Renta show on Monday. He is also expected to attend Marchesa’s show on Wednesday.

After three months of “working so diligently” on the collection, Lhuillier said it’s interesting to see how it tells a story. Birthdays aside, Lhuillier said, “This one was particularly personal to me because of that whole nostalgic journey of looking through my archives. I thought about what I wanted to bring back and what I considered relevant today. The feathered pieces were in my collections early on, like in 2000 or 2003. “

Once the birthday festivities are wrapped up, the designer will have one more gift for herself. “The best part of being done is sleep,” she said.
