Jacquard
Jacquard was an apparatus from the 19th century and is named after its inventor, Joseph-Marie Jacquard. It is attached to a loom and uses a punch-card system, which the loom reads like binary code — each card represents a line of the pattern and has holes that allow threads to pass through (or not), changing the colours and slowly creating the jacquard design. It allowed for more elaborate patterns to be produced in woven and knitted fabrics at greater quantities and speeds.
Keyhole Neckline
Keyhole necklines are a style of neckline similar to a halter-neck, where the converging diagonals of the neckline’s construction meet at the front. But rather than there being solid fabric here, keyhole necklines have a central cutaway — the keyhole — just below the collarbone.
