20s & 30s beach / ‘lounge’ pyjamas. They just ooze elegance & sophistication & are visually very iconic. Until the 1920s, pyjamas were pretty much only worn as sleepwear, then sometime in the 1920s they made their way outdoors as a cover-up over swimming costumes on the beaches of the French Riveria. When crepe pyjamas were first worn at the seaside, trouser wearing women were rare sight & still very much confined to beach & promenade areas.
