This study examined the influence of gender, type of social cause, amount of charitable support, and message appeal on Gen Y consumers' attitudes and purchase intentions towards an apparel brand within the context of cause-related marketing. A questionnaire, with an experimental design component, was administered to a sample of 562 Gen Y college students. Results suggest that Gen Y consumers are more likely to form positive attitudes towards an apparel brand when the amount of the charitable support is clearly communicated. Gender did not influence attitude towards brand, but did predict purchase intentions. Attitude towards brand, subjective norm, evaluation of the advertisement, and involvement in social causes were strong predictors of purchase intentions. When developing CRM initiatives, marketers should consider Gen Y's involvement in a social cause (e.g. volunteerism) rather than their stated interest in the given cause, and they would be well advised to state precisely (in advertisements) the amount of monetary contribution made to charitable causes.
