From the 20 February 1955 New York Times:

'America loves the long, lithe lines. Streamlining is an American specialty, and never have native designers done it better than in the fashion collections for spring. Now any woman can look slimer, taller, more serene and sophisticated than she ever has before. Clean cut, sparse detail and precise proportion all combine to produce this happy optical illusion which the smartest clothes in town convey.

The short suit jacket; the jacket barely covers the waistline and emphasizes the narrow hips of the slim skirt.  The crisp, dandified town suit is in black and white shepherd's check wool. A soft, white scarf fills in the neckline.  By Ben Zuckerman, about $225. Hat by Mr. John.'
