The Lou Lou crisp white rounded linen collar with black tulle. The collar is made from 100% Pure Irish Linen woven exclusively in Wexford, Ireland. One size fits all due to the 'slider' feature. Originally from the adjustable kilt, the 'slider' is a traditional yet minimal contemporary design in the neckband. It is a subtle and useful tool as it creates an adjustable collar for only the wearer to see and use.
