Bikram yoga is a form of Hatha Yoga that consists of 26 poses executed in a specific order for 90 minutes in a room heated to approximately 40°C (105°F) with 40% relative humidity. The purpose of this study was to understand the clothing needs for Bikram yoga practice, to investigate dynamic change of body dimension through anthropometric measurements in select Bikram yoga postures, and to propose improved designs to meet consumers' needs in performance and comfort. A mixed methods research approach was undertaken comprising of four parts: interviews with participants, anthropomorphic data collection, prototype creation, and follow up interviews. Participants voiced satisfaction with the final unitard prototype as having adequate support in the chest area however also stating that the ruching in the mid-section of the garment was 'baggy' relative to their body type.
