Double knitting

[2] Double knit fabric became popular within 1970s fashion; in the 1988 Grammy Award–winning song "Parents Just Don't Understand", Will Smith comically excoriates his mother for forcing him to wear outdated, 1970s-era "double-knit reversible slacks".

However, the double-knit fabric referred to is a machine-made, double-thick construction with some similarities to handmade double knitting (durability, reversibility) but none of the unique colorwork and construction possibilities.

Scuba knit fabric is a lofty double knit fabric, that was designed to mimic neoprene,[3] made from finely spun polyester fibers commonly with 2 way stretch that has a super smooth hand on both sides, low luster sheen and a full-bodied drape.

Switching colors ties the two sides together for a single, double-thick fabric.

The finished item from this method is reversible, each side holding the negative image of the other.
