We care about educating the masses about some of the unethical practices in the fashion industry and how our small changes can make a difference. However, our research has found that the switch to ethical shopping is a gradual one. Shoppers will continue shopping at fast fashion brands such as ZARA and H&M. We exist to encourage you to make incremental changes by reducing the amount of clothes you return, to start with. We will be working more closely with sustainably-minded retailers to make it easier for you to find alternatives to fast fashion.
efitter only works on Google accounts. If you have a Gmail account, you could forward your email receipts from your Yahoo email to your Gmail email.
Unfortunately, efitter is only available on Google Chrome.
In order for efitter to work effectively, you would need a history of online purchases and to have your order confirmation emails in your inbox. efitter will start making size recommendations from your very first order.
efitter works best on womenswear however, if the menswear you buy uses unisex sizing, we’ll be able to help you find your perfect fit!
Currently, efitter predicts UK sizes only.
1. Remember to click “reload your emails” in the extension so that we have the most up-to-date information about your past orders.
2. Double-check that any orders you have placed were from the last 12 months. To give you the most accurate size prediction, efitter will only recommend a size based on the last 12 months of orders.
3. If you are sure you have order confirmation emails from the last 12 months, you may have shopped with a brand whose emails we don’t recognise yet. Send us an email with the name of the retailer(s) you shopped with and we’ll look into it.
4. Still having issues? Get in touch and we will be happy to help.
efitter uses your past orders to predict your size but that might be inaccurate, especially if you share your account with someone else. In that case, get rid of any order confirmation emails that don’t belong to you, then click “reload your emails” in the extension. Remember that some retailers use European sizing which may look completely different to the sizes you are used to.
Since efitter uses your orders from the last 12 months to predict your size, if your size has changed in the last few months your prediction may be a bit out of date. You can test this by using efitter on a website where you know your size and if you are recommended your old size, size up or down as appropriate.
efitter will do its best to predict your size but you know your body best - feel free to tweak your recommended size based on whether you like your clothes to fit tight or loose too.
No problem - reach out to us and we’d be happy to help.
