In Roman Holiday Peck captured the suiting style of a generation with enormous shoulders, a ventless jacket, pleated pants, and lapels nearly wide enough to take flight. It set the stage for The Man in the Gray Flannel Suit -- an entire movie dedicated to Peck in the suit that defined an entire era. The color was corporate and anonymous, marking the beginning of a post-WWII culture built on business.
Although Peck spends the film suited up(though he does roll up his sleaves at times) Rome was a place for leisure. In the 1950s polo shirts and short-sleeved button-front shirts in bold new designs gave men the opportunity to express themselves as individuals and long-sleeved button-front shirts also became available in bright colours.
A popular way to wear shirts was open at the neck and with the sleeves worn rolled up to the bicep. Cardigan sweaters worn over button-front shirts or polo shirts were frequently worn when dressing was casual. Hawaiian shirts were bright, bold and colorful. When a jacket was required, many men chose patterned sports jackets made of wool.
The Italian look, popularized by Caraceni, Brioni, and Cifonelli, was taken up by an entire generation of elegant young lovers, on both sides of the Atlantic. Plaid was very common in 1950s men's fashion, both for shirts and suits, along with the "ducktail" haircut, which was often viewed as a symbol of rebellion and banned in schools.
