More tinsel refers to the addition of glitter and decoration to an already decorative item. In contrast, the antonym for more tinsel would be simplicity or minimalism. This can be seen in design, fashion or even in language. While tinsel adds an element of loudness and sparkle, simplicity offers a more subdued and elegant look. Minimalism is all about paring back to the essentials, which means reducing the amount of decoration rather than adding more. If more tinsel represents excess, then simplicity emphasizes balance, minimalism and elegance in its purest form.
