The Mirabelle is made by our factory in Porto, Portugal. A family run business, this factory has been part of the Beaumont Organic supply chain since we launched 10 years ago. We speak to the team at the factory almost every day and visit regularly to maintain a great working relationship. We give the factory long lead times to ensure they are not rushed and do not need to work unsociable hours to achieve deliveries.


The fabric used in this still is GOTS certified organic cotton. GOTS certification is an independent guarantee that the cotton has been farmed in line with organic practices and that all workers involved in the production have been paid a fair wage. To find out more click here

Clothing should be comfortable and effortless. We believe the better you feel in your clothing the better you will look. Therefore our clothes are designed to ensure you feel comfortable, whist also looking elegant, with a looser cut that does not feel restricting.


As women our bodies are constantly changing, responding to monthly hormonal cycles or having children. As a sustainable brand we make clothes to stand the test of time and this is another reason why we choose to design loose fitting pieces that can stay in your wardrobe for many years to come.
