Italian size conversion

All sizes on the site are Italian. Use the table below to convert them.

Women's sizes: Pinup and Ibiza

Pinup and Ibiza come up small: go one size up from your clothing size. Wear a 44 → choose a 46. Stick to your usual size only if you want a very snug fit.

Pinup goes up to 46. For a 48, choose Ibiza or Maui; some Ibiza prints go up to 50 and 52.

Ibiza has a more closed back and gives more support and tummy control; the sizing rule is the same. Maui, New York, Bondi and Malibu fit true to size: go one up if you prefer less compression.

Men's sizes: H2otto, Ucla and Alaska

H2otto: clothing size 46 is an L, 48 an XL, and so on. Ucla and Alaska follow your clothing size.

All of them have a drawstring waist. If you don't like a tight swimsuit, go one size up for comfort around the thighs too.

Training swimwear

Pinup, Ibiza, Maui, H2otto and Ucla are made in Speed Line by M.I.T.I., 100% PBT polyester; Milano and the BONESWIMMER x Vira capsule (New York, Alaska, Bondi, Malibu) in 51% recycled polyester and 49% PBT. There is no elastane in the yarn: the swimsuit resists chlorine and keeps its shape and colour for a long time, even with daily use. The exact composition of each piece is on its product page, under «Materials and care».

To work properly they need to fit like a second skin: it's normal to struggle getting them on. In the water everything settles and the swimsuit becomes comfortable and stable.

Beach and leisure swimwear

Alte, Dega, the Santorini, Tahiti, Big Sur, Hawaii and Papeete bikinis, the Samoa swim shorts and the kids' beach swimwear contain some elastane: they're easier to put on and comfortable out of the water too, all day long. Choose your usual clothing size: over time the fabric adapts to your body.

These pieces are sensitive to chlorine: always rinse them straight after the pool.

Care, for every swimsuit

Rinse in plenty of cold water after every use (chlorine, salt, sun cream) and dry in the air, away from heat and direct sunlight. That way lining, seams and colours stay as good as day one.

• NO washing machine
• NO tumble dryer
• NO detergents, unless made for sportswear
