INTRODUCTION
Over the years, the organizations have captured the global market based on different product attributes. But, now, the constant media coverage has colossally numbed the marketing standards by hooking the consumers' attention toward the modern branding. The brisk proliferation of digital media has considerably inspired companies to accelerate their promotional activities via celebrity endorsement. Indeed, these profound marketing strategies have made celebrity endorsement a vital knob, grasping the consumers' considerations (Qureshi and Malik, 2017) concerning purchase tendencies (Lin et al., 2018).
However, in modern advertising, the impulsive buying tendency has evolved for years, thus making this unique phenomenon to increase the consumers' gratification (Pradhan et al., 2018). The rising impulsive tendencies have maximized the individuals' urge for the store products. Consumers' impulsive buying tendency alludes to unplanned buying (Malter et al., 2020). It is a persuading power that makes the consumer realize the need for the textile product. In recent years, the increasing market competitiveness has made it difficult for marketers to foster consumers' impulse buying tendencies. However, after years of constant struggle, the global textile industry has again gained height by making consumers recognize the need for fashion products.
Undoubtedly, today, the consumption of clothing items has become the norm for the young generation who uses fashion to express themselves. The increasing desire for the newest products has made the consumers indulge in impulsive buying. Notably, for investigation, this study chooses the textile fashion industry because it profoundly captures the materialistic essence of impulsive buying tendencies, satisfying the individuals' urge for the product . However, today's fashion industry is at its boom and demands effective marketing strategies to capture consumer attention. The consumer purchase intention as the outcome of spontaneous encounters encourages the consumers to realize the need for the product (Maharani et al., 2020). In particular, this escalating impulsive tendency demands that organizations adopt celebrity endorsement strategies to influence individuals' buying intentions. In the textile industry, consumers' choosing the high-value product needs the recommendations of some authentic source. Unlike traditional marketing, celebrity endorsement characteristics have become an essential credential for driving the consumers' impulse behavior.
Celebrities play a vital role in boosting the sale of fashion products. Celebrity branding provides symbolic information to the consumers' , thereby assisting their buying behavior. Accordingly, the study shows that the celebrity's desirable characteristics (i.e., trustworthiness, attractiveness, credibility, and expertise) harness the brand advertising (Lou and Yuan, 2019), thereby influencing the consumers' decisions. Hence, the inherit literature makes it necessary for the researchers to study the endorsers' characteristics concerning the consumer buying intention (Zhu et al., 2020).
Celebrity endorsement is an effective marketing strategy that captures the buyers' attention toward elevating brand awareness. In this regard, celebrity trustworthiness act as a credible source that enhances the buyers' purchase intention. Celebrity trustworthiness forms a positive customer perception, thereby making them buy the product.

Trustworthiness is a significant construct that refers to the endorsers' dignity and believability. In advertising, the perceived source trustworthy makes the consumer comply with the brand message. This effective brand promotion makes the celebrity attribute (e.g., honesty, trustworthiness) increase the efficacy of consumers' purchases. Given the illustration, the study shows that the greater the endorsers' trustworthiness, the more the consumers find them convincing and honest (Djafarova and Rushworth, 2017).
In particular, the celebrity persona also plays a profound role in increasing brand recognition. Celebrities are the prominent icon that influences the organizations' success in various fields. They wind up the brand sales, thereby forming a positive brand image in the minds of the consumers. Celebrity attractiveness promotes the firm's offering, thereby assisting individuals in making brand choices (Kumar et al., 2019). The celebrities' physical attraction plays a fundamental role in providing an advantage to the markets to promote their brands' offerings. Customers often buy products based on their likeness. This source of endorsement makes the customers feel that the celebrity's attractiveness complements the brand's features. In particular, celebrity attractiveness assists customers' purchase choices, thus motivating them to buy the product (Onu et al., 2019).

Given the explanation, the study states that celebrities' credibility elevates the firms' marketing activities, thereby influencing impulsive buying behavior (Koay et al., 2021). Besides celebrity credibility, endorsers' expertise also plays a fundamental role in convincing the customers to buy the product. Customers spend less time planning and rely on the endorser's expertise to guide their purchase choices. The significant changes brought by the novel marketing strategy have fundamentally made the customers alter their purchasing patterns (Zia et al., 2021). However, in this regard, celebrity expertise plays a fundamental role in fostering the firm's branding. Expertise refers to an individual's qualification, skills, knowledge, and competency (Hovland et al., 1953). The leaders' competence enhances the consumers' understanding, thus persuading them to buy the product. Based on the statement, the study shows that most of the audience evaluates the advertising message based on the source's competence (Wang and Scheinbaum, 2018). Therefore, the literature depicts those celebrities with high personal characteristics are perceived to be more persuasive in influencing individual purchases.
Indeed, the above research concludes that celebrity traits profoundly improve consumer purchasing power (Lou and Yuan, 2019). Accordingly, previous literature reveals that in older days, marketers' used different cues (e.g., store appearance, product packaging, shelf display, and store layout) to influence consumers' buying behavior (Husnain et al., 2019). However, today, celebrity advertising has considerably grabbed the consumers' attention, thereby enhancing their buying intention. Indeed, this prior literature makes it essential to understand the role of celebrity personality traits in influencing consumer behavior. Based on this statement, the study suggests that researchers should investigate the role of a celebrity's characteristics (e.g., trustworthiness, attractiveness, credibility, and expertise) in influencing consumers' impulse buying and purchase intention (Martensen et al., 2018).
However, against this drop back, this study examines the impact of celebrity characteristics (e.g., trustworthiness, attractiveness, credibility, and expertise) on consumers' impulsive buying. Significantly, the study objective is to identify the influential factors that predict consumer purchasing intention in the textile fashion industry. Indeed, this study incorporates a suitable conceptual model for evaluating the relationship between the variables.

Therefore, based on prior research findings, we have concluded the following hypotheses: H3: Attractiveness of celebrity endorser has a positive and significant impact on impulse buying tendency. H4: Attractiveness of celebrity endorser has a positive and significant impact on purchase intention.
The Credibility of Celebrity, Impulse Buying Tendency, and Purchase Intention The use of celebrities in the brand advertisement has made the consumers direct their perception regarding the brand offerings.
