STUDIO I STEPS OUT: Studio I, a New York-based moderate-price dress and suit firm, has opened a misses’ evening dress division for spring under the Studio Nite label. The collection is designed by Linda Bernell, who also designs the firm’s Delaru junior evening dress collection.

Debbie Baron, formerly in sales at Karen Kane Co., has been brought in as sales manager for Studio Nite. She reports to Fattameh Bahari, president and a principal in the firm. Bahari also designs the Studio I collection.

The new line wholesales for $59 to $125. It features such fabrics as rayon crepe, polyester and rayon chiffons, embellished with re-embroidered lace and beading. Studio Nite projects sales of about $5 million in the first year. It will share showroom space with the Delaru line at 1400 Broadway.

CARDLIN DIRECTS HOOK LINE: Pat Cardlin has been named director of the licensed J.G. Hook Dress division of the Et Al Group, New York.

Cardlin’s duties include merchandising, marketing and sales. She formerly worked in sales for the J.G. Hook Dress and Suit division of the He-Ro Group when that company held the license. Et Al got the Hook dress license in November.

Cardlin will work with Eric King, a vice president at Et Al. King projects first-year sales of about $10 million.

Ronnie Rosado has rejoined the company as fashion director and designer for the Et Al collection. Rosado was a designer with the firm from 1985 to 1989. She was head designer at Eneste here from 1989 until her reappointment at Et Al.
