Fit Guarantee

Fit Guarantee – Your perfect size, worry-free

Shopping online can make choosing the right size tricky — we understand that! And during your period, comfortable, well-fitting underwear or a properly fitting bra is extra important. That’s why we offer our Fit Guarantee with your first order.

How does the Fit Guarantee work?

Not sure about the size? No problem. With your first purchase, you’re allowed to try on the underwear or bra.
Not the right size after all? You have up to 7 days after delivery to let us know and make use of the Fit Guarantee.
You can exchange your underwear or bra once for a different size — even if the hygiene seal has been broken. We’re happy to help you find the right fit.

Who is the Fit Guarantee for?

All first-time purchases — you can use the Fit Guarantee with your very first order from us.

How do you exchange an item?

Send an email to info@lunasperiod.co.uk within 7 days of receiving your order and let us know which size you need. Our customer service team will take care of everything for you.

Products provided under the Fit Guarantee are shipped free of charge — you only pay the shipping costs. As no product costs are charged for these replacement items, no refund applies if they are returned.

What do I pay?

For the Fit Guarantee, you pay a one-time fee of £6.95, which covers the shipping costs for the exchange.
