• 1800s — Cotton companies were massed-producing undies like the union suit, a full body style with ranging sleeve lengths.
• 1930s — Companies began selling what were the first boxers shorts. And in 1934, Jockey debuted Y-vent briefs.
• 1960s — With the invention of materials like nylon and Lycra, underwear got more comfortable and more colorful.
• 1982 — Calvin Klein posted a billboard in Times Square of a guy in briefs, which made heads turn.
