Cilium, formerly known as TILLYandWILLIAM, is a clothier with a philosophy that celebrates and explores innovation, transformability, and gender non-exclusivity. At the nucleus of Cilium is designer Tilly d Wolfe. They spent years crafting Cilium to align itself with active social and environmental responsibilities in regards to the sourcing and production of its wares while seeking new and ancient technologies for unyieldingly comfortable and sustainable materials. 


Cilia can transform to suit multiple uses, as you’ll see throughout the site. There is no wrong or right way to wear cilia. Each garment is meant to create a unique relationship with the individual as they/she/he/ze/hir continue to experiment with them over time.


The goal is to extend the use of clothing, thinking about the ways in which you may use it throughout a given day as well as how it can evolve across a lifetime. Creating pieces that move in rhythm with our physical needs and possess the ability to transform in tandem with our ever-changing sartorial desires.




The Cilium Studio is located in Brooklyn, NY.

cilium (pl. cilia)

(biology) Membrane-enclosed motile structure extending from the surface of eukaryotic cells. Cilia usually occur in groups and beat rhythmically to move a cell (e.g., single-celled organism) or to move small particles or fluid along the surface (e.g., trachea cells). See also axoneme and flagellum. Microscopic, hair-like projection on the surfaces of some cells and of certain organisms.


(botany) Any of the hair forming a fringe along the margin or edge of a plant structure, e.g. of a leaf.


(anatomy) The eyelash.



Cilia are generally of two kinds: motile cilia (for [[locomotion]]) and non-motile cilia (for sensory). Example of tissue cells with cilia are the epithelia lining the lungs that sweep away fluids or particles. Examples of organisms that have cilia are protozoans that use them for movement.
