And to help reduce waste, Aspiga has a handy repair and rewear service. It also makes upcycled accessories, including wash bags, scrunchies, and face pads from scrap fabrics leftover from production that in fabrics that would have otherwise gone to landfill.

More Ethical Places To Try

If buying a new dress is out of your budget, then there are heaps of other sustainable ways to dress ethically for parties:

• Try borrowing from a friend. Particularly when it comes to occasion wear, many of us wear an item only a few times, so it’s a good way to get the most from existing items.
• Try shopping preloved. I have a handy guide to the best places to shop online for secondhand clothing, if you don’t have time to visit your local charity shops.
• Alternatively, you could try renting a dress. Places to try include By Rotation, Hurr, and John Lewis. Here you can rent iconic and independent designer brands from as little as £20.
