In the 1930s, women wore full length gowns for evening. Body conscious jersey knits and bias cut satins revealed a woman's curves and these looks were very sexy. Fuller skirts were also available, though not nearly as full as they would be in 20 years time. While bare arms dominated, if a gown had sleeves, they were quite full and dramatic. Today, evening dresses from 1935.
