After a smaller, capsule collection for the famed bridal shop, Siriano teamed with Kleinfeld again on a broader range.

His show stopper was a pricey pink ombre ball gown with a sweetheart neckline and skinny straps. As an evening wear designer, Siriano said bridal was a natural fit. He created in a range of sizes up to 24 or 26 - and a range of price points from about $3,500 to about $19,000.

Noting most dresses can be modified, he showed a lot of sleeves. There were long lacy ones on a column gown and a structured, off-the-shoulder pair in satin, embellished with tulle and strings of pearl.

One of his mermaid gowns included cascading ruffles. He used four tiers of ruffle at the bottom of a white, tailored suit jacket with matching boot-cut trousers.

Siriano also offered a range of hem lengths, from well above the knee in an appliqued mini to a fitted tea length with an ornate high neck and dramatic train.

In a backstage interview, Siriano said he's enjoying his first full push into bridal with the 27 pieces for Kleinfeld after focusing most of the time on evening.

"But the customer is so different," he said. "There's not as many rules. You can get away with trying new things, doing new things. It's a little fantasy dream world."

And what will Siriano wear when he weds his longtime boyfriend, Brad Walsh, at their Connecticut house this summer?

"I don't know. Literally we've got nothing," Siriano laughed.
