It's not hard to imagine the social schedule of the woman who'll snap up the rock crystal-strewn white linen trench or black linen sheath Andrew Gn showed for spring. Lunch at BG, dinner at Le Bernardin, box seats at the opera, season tickets to the ballet. Gn designs for a customer who likes her clothes as precious as her jewels—and doesn't have cause to worry about the dry-cleaning bills. Nary a collar, hem, or cuff came unembellished, and this season, even button closures got the royal treatment.

Working in black, white, beige, and metallics, Gn kept the show's silhouette short and narrow. Perhaps the richest offering was the coat cut from a silver silk brocade made to resemble crocodile skin. But he also added python to his repertoire, trimming the puffed sleeves of a bolero in the stuff or using it as the basis for an anthracite abstract silk print.

It's a rarefied world Gn calls home, and to be sure, this show felt repetitive near the end, as one short ombré-beaded skirt came out after another. Don't his ladies have occasion to wear pants? Elsewhere, though, he had his eye sensibly on growth. A one-shouldered cocktail number with a silver sequined serpent coiling from the asymmetrical neckline to the waist should get the youth vote.
