Women's Chemise (Sleepwear & Robes)

A chemise is a nightdress cut like a slip: thin adjustable straps, no sleeves, no buttons, and a hem that lands between the upper thigh and just above the knee. Nothing on it fastens. You pull it over your head and it hangs from the shoulders, with no waist seam to pin it anywhere.

Most are cut on the bias, meaning the pattern pieces are laid at 45 degrees to the weave so the cloth stretches diagonally. That diagonal stretch is why a silk chemise follows the body without any elastic in it, and also why it can grow slightly through the hip after several wears. Bias cutting also makes the side seams spiral a little rather than run straight down, which signals a well made one rather than a fault.

Length and register separate it from the rest of the shelf. Nightgowns run longer, often to the calf or ankle, usually carry sleeves and have a fuller skirt. So they read as sleepwear rather than lingerie. Sleep shirts button down the front and are cut boxy from shirting cloth. Pajama sets cover the legs; a chemise deliberately does not. Slip dresses in the dress department use the same shape in heavier fabric with seams finished for daylight.

Hot sleepers gain the most, since a bias silk layer weighs almost nothing and lets air move across the skin. Warm climates, summer months and anyone tired of fabric bunching at the waist are the other cases. A bedroom in the low 60s Fahrenheit rules it out, and so does any night you expect to be up with children or pets.

Strap adjusters deserve the first look, because the whole garment hangs from them and a fixed strap leaves you no way to correct the hem height. Pinch the fabric to test the fiber: real silk warms in your hand within seconds while polyester satin stays cool and slick. Silk wants a hand wash in cool water with a mild soap, then a roll in a towel to press the water out and a flat dry away from sunlight, which yellows it over months.
