Question

Which figure of speech is used in this text?
Savannah's Boutique claims to have "something for everyone," but it is generally understood that their target market is women of a certain age.

Answer 1

This is irony — there’s a clear contrast between the boutique’s claim ("something for everyone") and the reality (their customers are actually a specific demographic). The advertised phrase itself is also a hyperbole (an exaggerated generalisation).
