Quality Analysis 60/100
This swimsuit is made from a smooth peau douce fabric, a blend of 77% polyamide and 23% elastane, which suggests good stretch and recovery for swimwear. However, the "hand wash" care instructions and warning about discoloration from lotion, sunscreen, oil, and chlorine indicate that careful maintenance is required to preserve its appearance and longevity.
Comfort Assessment 90/100
This swimsuit promises a delightful feel with its "smooth peau douce fabric" and a generous 23% elastane, ensuring a comfortable, flexible fit that moves with you.
Sustainability Impact 60/100
This swimsuit is made from conventional polyamide and elastane, which are fossil-fuel-derived synthetics without any mention of recycled content, indicating a lower sustainability profile.
