Size Inclusivity Drives Consumer Loyalty and Market Share in Ready-to-Wear Fashion

Why It Matters

Understanding the psychological impact of body image on consumer choices is crucial for developing effective market strategies. By adopting size-inclusive practices, brands can tap into a broader customer base and foster stronger relationships, ultimately enhancing their competitive position.

Key Finding

Consumers' feelings about their bodies strongly influence the clothing sizes they prefer and how they shop. Those unhappy with their body image may buy clothes differently, while brands that show a range of sizes in their advertising appeal to more people.

Key Findings

• A significant correlation exists between body image satisfaction and clothing size selection.
• Individuals with negative body image tend to exhibit compensatory purchasing behaviours.
• Positive body image is associated with greater flexibility in size choices.
• Retailers employing size-diverse marketing strategies garner more favourable consumer reactions.

Research Evidence

Aim: To investigate how body image perception influences garment size preferences, brand selection, and overall shopping experiences within the ready-to-wear fashion market, and the effect of size-inclusivity initiatives on these behaviours.

Method: Quantitative survey research

Procedure: Data was collected from university employees using a group-administered questionnaire to assess the relationship between body image satisfaction, clothing size selection, brand preference, and responses to size-inclusivity.

Sample Size: 238 participants

Context: Ready-to-wear fashion consumption in Ghana

Design Principle

Embrace diversity in product offerings and marketing to enhance consumer engagement and market penetration.

How to Apply

Conduct market research to understand the body image perceptions and sizing preferences of your target demographic. Develop marketing materials that showcase a diverse range of body types and sizes. Ensure your product lines offer a comprehensive size range.

Limitations

The study was conducted within a specific geographical and demographic context (university employees in Ghana), which may limit the generalizability of findings to other populations or regions.

Student Guide (IB Design Technology)

Simple Explanation: If fashion brands show clothes on different body types and offer many sizes, customers will like them more and buy from them more often.

Why This Matters: This research highlights how understanding user psychology, specifically body image, can directly influence market success and consumer behaviour, which is vital for any design project aiming for commercial viability.

Critical Thinking: To what extent can a brand's commitment to size inclusivity genuinely address societal body image issues, or does it risk commodifying these concerns for profit?

IA-Ready Paragraph: Research indicates a strong link between body image satisfaction and consumer behaviour in the fashion industry, with size-inclusivity initiatives positively impacting brand perception and market share. For instance, a study by Siaw et al. (2025) found that retailers incorporating size diversity in their marketing strategies received more favourable responses from consumers across the body image spectrum, underscoring the commercial advantage of inclusive design and marketing.
