COS I SAID SO – Organic Brand For The Urban Mini-Malist All garments of the COS I SAID SO collection are made out of comfortable, organic/bci cotton, so your little one will enjoy wearing them. We believe good quality is key, especially since baby clothing gets worn so thoroughly. The look of COS I SAID SO is very minimal and mostly unisex. We use certified organic yarn for all items. CISS® supports the BCI. All designing and printing is done in Antwerp, Belgium.
