  • Buy less, choose better: think cost per wear.
  • Care for clothes so they last: wash cooler and less often.
  • Repair, resell, swap and donate before you throw away.

Six habits

  1. Shop your wardrobe first

    Before buying, look for what you already own that could do the job.

  2. Think cost per wear

    A coat worn 100 times costs less per wear than one at a third of the price worn five times.

  3. Wash less, and cooler

    Air knits, spot-clean marks, and wash at 30 °C when you can.

  4. Repair

    Sew on buttons, fix hems, resole shoes; many shops offer repairs.

  5. Buy second-hand

    Charity shops, vintage stores and resale apps keep clothes in use.

  6. Pass it on

    Sell, swap or donate what you don’t wear; recycle what’s worn out.

When you do buy

  • Choose pieces that go with at least three things you own.
  • Check fabric and stitching quality.
  • Look for brands that tell you where and how their clothes are made.

Questions

Wear the clothes you already have for longer.

Buying second-hand keeps clothes in use and avoids making new ones, which is usually better for the environment.
