Comparative: more decollete
Superlative: most decollete
Decollete → It is formed from "de-" (meaning down or away) and "collet" (from French, meaning neck or collar). The word refers to a style of clothing that exposes the neck and shoulders, hence the idea of lowering or removing coverage from the neck area.
Think of 'down' ('de-') and 'neck' ('collet') to remember that 'decollete' refers to a style that reveals the neck.
