Redefining vanity sizing: when bigger may be better

Purpose: Although vanity sizing has often been conceptualized as “smaller is better” in apparel sizing, this perspective is limited in that many products would be more negatively perceived if viewed as smaller in size. In such scenarios, “larger is better” would be a more appropriate heuristic. Thus, vanity sizing should be redefined as a practice in achieving social desirability in size labeling. Namely, vanity sizing actually seeks to induce feelings of either smallness or largeness depending on the context. The purpose of this paper is to address this redefinition. Design/methodology/approach: The current research provides initial empirical support of this redefinition with two studies that utilize a blended qualitative/quantitative approach and a hypothetical product scenario in which “larger is better” (bras). Findings: Study 1 indicates that consumers seek to feel smaller and larger across different bodily areas. Further, study 2 found that compared to consumers of larger cup sizes, consumers of smaller cup sizes react more favorably to larger-than-typical cup sizes, forming more positive cognitive/affective reactions. Further, these cognitive/affective reactions influence purchase intentions, confirming findings of prior literature concerning attitudes and purchase intentions. Overall, the findings support the need to redefine vanity sizing. Originality/value: The present conceptualization of vanity sizing is too narrow and limits understanding of the implications of vanity sizing across all sizing situations. Thus, this paper redefines vanity sizing and furnishes empirical evidence that such redefinition is warranted.
