IPA: /ʌnˈʃɪk/
KK: /ʌnˈʃɪk/
Not stylish or fashionable; lacking in elegance or trendiness.
The dress she wore was considered unchic by the fashion critics.
Unchic → It is formed from the prefix "un-" (meaning not) and the root "chic" (from French *chic*, meaning stylish or fashionable). The word "unchic" means not stylish or lacking in fashion.
Think of 'not' ('un-') being added to 'stylish' ('chic') — that's why unchic means not stylish.
