TILLAA CIRCULAR, our mid waist skinny detox denim goes one step further in terms of circularity. Each pair consists of 20% recycled organic cotton - from recycled residues and waste from our own production. In addition, it provides you with a figure-hugging fit and comfortability. To keep this denim circular, we use a button that can be unscrewed from the jeans. Therefore, we recommend washing these pants in a laundry bag so that the button is not getting lost during washing.
