The fabric is the first difference, and the most significant
Most fast-fashion swimwear is made from nylon or polyester blended with elastane. These fabrics are functional, inexpensive, and widely available. They do the job of holding shape for a season, sometimes two.
Luxury swimwear at the premium end uses Italian technical fabric: specifically, fabrics produced by mills in northern Italy that have developed formulations for superior stretch recovery, chlorine resistance, and colour retention. The difference is measurable. A bikini made from Italian technical fabric will hold its shape and colour after fifty wears and fifty rinses. The same piece in a commodity blend will begin to lose elasticity and fade after a fraction of that.
Paolita’s swimwear is produced in Italian technical fabric across the SS26 range. The Amalfi Arabella bottom and Azania one-piece are additionally made from premium recycled fabric, which goes through the same performance testing as virgin technical fabric while meeting a more demanding materials standard.
