Marysia
Ex-ballerina and keen surfer, Marysia Dobrzanska Reeves, spent much of her early life wearing leotards and wetsuits, so when she launched her eponymous label in 2009, she had an intrinsic understanding of how specific materials and cuts could favour the female form. Opt for a signature scallop-hem swimsuit, or explore the wider range of classic bikinis and one-pieces.

What is a high-quality swimwear material?
High-quality swimwear materials are essential for durability, comfort, and fit. Nylon and lycra blends are commonly used due to their excellent stretch and shape retention, while polyester is another durable option that is resistant to chlorine and UV rays, making it ideal for avid swimmers. Additionally, PBT (Polybutylene Terephthalate) is a high-performance polyester variant known for its resistance to chlorine and fading. These materials are often used by the best swimsuit brands to ensure long-lasting and comfortable swimwear.
What is the best mature swimsuit brand?
When searching for swimwear later in life, it’s important that you choose something comfortable, that makes you feel your best. Marks & Spencer is a great (and affordable) choice, offering a number of different cuts that are both comfortable and flattering. Similarly, Melissa Odabash and Matteau have a selection of swimsuits made from high-quality materials that feel smooth and are gentle on the skin.
