What material is my OB clothing made from, and how should I wash it?
The OB Fashion Team's trained designers, buyers and garment technologists work collaboratively with our suppliers to select lower-impact materials where possible, while still maintaining the distinctive design-led details we’ve come to be known for. You can find the material breakdown of a specific clothing product on the individual product page.

Look inside your OB clothing and you’ll find a small care label with UK and EU-regulated symbols for washing, drying and caring for your clothes. You should always check the care label before washing your clothes – this will help to keep them in good condition for as long as possible. Read our washing guide, for advice on hand-washing, machine washing and a handy list of common wash care symbols, and find in-depth care and repair advice in our fashion care guides.

Can I buy pre-loved OB clothing or recycle items I no longer wear?

We’ve partnered with Reskinned to ensure our products are repurposed and recycled, and there’s two ways you can get involved. Shop reconditioned and as-new Oliver Bonas pieces on Reskinned’s pre-loved shop, or trade in your Oliver Bonas clothing, footwear, accessories and bags for up to £25 off your next brand-new Oliver Bonas order using their takeback scheme.
