Product care.

For us, building a sustainable brand is a non-negotiable, not a nice-to-have. That includes how our products are used and cared for by you at home. You can look after your ®WILHELM pieces and help them to last by:

Washing inside out.
Using eco-friendly detergent.
Air drying where possible.
Ironing only if needed.


Product fit.

Fit for purpose and sized for optimum comfort and freedom, see our size charts below
