POCCosiol clothing brand ownership is identified as people of colour.
LGBTCosiol was founded by designer Klaudia Kasinska, a woman who started the brand just after her fashion studies as a passion project that began in 2017 as Marii Aneett and evolved into Cosiol in 2021.
Woman OwnedCosiol clothing brand is a woman owned clothing brand.
1% for the planetCosiol clothing brand is not a member of 1% for the Planet.
Feature 1Cosiol crafts its clothing using natural linen, wool, hemp and organic fabrics, and its sustainable items are made of 100% Natural European Flax, a natural fibre drawn from the flax plant Linum usitatissimum. Alongside these fibres, Cosiol uses Pinatex, a non-woven textile made from pineapple leaf fibre that is a by-product of the agriculture industry and is described as 100% vegan and PETA approved.
Feature 2Every Cosiol garment is made in Europe through small-scale production that values quality, craftsmanship and a lower environmental impact. Packaging for Cosiol is produced in Poland from 100% FSC-certified material that is 100% recyclable and biodegradable, though no specific factory or supplier names are disclosed.
Feature 3The European Flax linen used by Cosiol carries the European Flax quality visa, which guarantees zero irrigation, zero GMOs and zero waste. For its Pinatex, Cosiol notes that the dyes are GOTS approved and the resins comply with AFIRM standards, and Cosiol frames its wider practice around responsible manufacturing, a slower approach to fashion and vegan design.
ShippingCosiol delivers worldwide, using DHL and DHL Express for European and international orders and MRW for domestic orders. Duties and taxes on international Cosiol orders are the responsibility of the customer, as the price does not include duty and tax fees for international orders.
Shipping InternationalCosiol ships internationally, delivering European and international orders with DHL and DHL Express, while duties and taxes on international orders are the responsibility of the customer.
Shipping NotesFree shipping from Cosiol applies on orders over 40 euros in Spain and Islas Baleares with the code FREESHIP, with Canarias excluded, though the site separately states free shipping for purchases over 200 euros in Spain, so the free-shipping threshold is stated inconsistently.

How Cosiol compares across published ratings
Wear it longer
Work out the real cost per wear
Use the price and realistic wear count to compare long-term value.
£0.00 per wear
Cost per wear is the honest test behind "buy less, buy better": a £200 coat worn 300 times beats a £25 one worn 5 times. It rewards wearing what you own and choosing things built to last.
