Douglas Hannant’s spring collection blew in on a warm, tropical breeze. Presented on the roof of the Hudson Hotel, the collection played well against the river view and the bright sky. Mr. Hannant’s prints looked especially winning: Several pieces — a flowing gown, day dresses, and blouses — were made from a sheer fabric printed with ginko leaves. Short hemlines for a tent dress and A-line dress, cut from a blue mosaic patterned fabric, made the mood dreamy; both dresses had fitted sheaths under flowing layers that gave the illusion of two dresses in one. Only a few suits were presented, and one baggy jacket was an unflattering misstep. But that was quickly forgotten when followed up by easy pieces, such as a beaded silk caftan, and dramatic stunners, such as a white charmeuse gown accented at the hip with a colorful mosaic medallion. While that gown clung to the body, there was more forgiveness in the powder blue halter gown with honeycomb stitching and billowing fabric; with all its loose and casual flair, it purred contentedly: “She’s gone to Capri, and she’s not coming back.”
